Victoria spent 5 9 of her money on a cake and two meat pies. Each meat pie cost 1 6 as much as the cake. She had $24 left.
(A) How much did victoria spend?
(B) How much did the cake cost
Let's assume Victoria's total money is M.
She spent 5/9*M on a cake and two meat pies.
Let's assume the cost of the cake is C.
So the cost of two meat pies is (1/6)*C.
The total amount she spent on the cake and two pies is C + (1/6)*C = (7/6)*C.
We know she had $24 left, so 5/9*M + (7/6)*C = M - 24.
Simplifying the equation, we get (5/9)*M - M = -24 - (7/6)*C.
Combining like terms, we have (-4/9)*M = -24 - (7/6)*C.
Multiplying both sides by -9/4, we get M = 54 + (63/8)*C.
Since M represents Victoria's money, it must be an integer value.
So the value of (63/8)*C must be a multiple of 8.
The only multiple of 8 in the given answer choices is 8, which means (63/8)*C must equal 8.
Simplifying the equation (63/8)*C = 8, we get C = (8*8)/63 = 64/63.
Therefore, the cost of the cake is $1 (rounded to the nearest cent).
To find out how much Victoria spent, we substitute the value of C into the equation (7/6)*C to get (7/6)*1 = 7/6 = $1.17.
So, (A) Victoria spent $1.17 (rounded to the nearest cent).
(B) The cake cost $1.
To solve this problem, we can break it down into steps:
Step 1: Determine the fraction of money Victoria spent on the cake and two meat pies.
According to the information given, Victoria spent 5/9 of her money on the cake and two meat pies.
Step 2: Determine the cost ratio between the cake and meat pies.
It is stated that each meat pie costs 1/6 as much as the cake. This means that if the cake costs x dollars, then each meat pie would cost (1/6)x dollars.
Step 3: Set up the equation to represent the total amount spent by Victoria.
Let's say the total amount of money Victoria initially had is S dollars. The equation representing the money Victoria spent is:
(5/9)S = x + 2(1/6)x
Step 4: Simplify the equation to solve for x.
To simplify the equation, we need to find a common denominator for the fractions on the right side:
(5/9)S = (6/6)(x) + 2(1/6)x
(5/9)S = (6/6)x + (2/6)x
(5/9)S = (8/6)x
Step 5: Solve for x.
We can solve for x by multiplying both sides of the equation by (9/5):
x = (9/5)(8/6)x
x = (72/30)x
(30/30)x = (72/30)x
1x = (72/30)x
Simplifying further, we get:
1 = 72/30
To solve for x, we need to plug in the value of S, which is given as $24. Let's substitute it into the equation:
1 = 72/30
1 = 2.4
Since the equation is not correct, it means there is a mistake in the question. Please review the question, and let me know if there are any adjustments or corrections that need to be made.
Let's break down the information provided step-by-step.
Step 1: Calculate the total amount of money Victoria had.
We are told that Victoria had $24 left after spending money on a cake and two meat pies. Therefore, we can subtract $24 from the total amount of money she had to find the initial amount.
Total amount of money = Amount spent + Money left
Let's denote the total amount of money as X. So, we have:
X = Amount spent + $24
Step 2: Calculate the cost of the cake and two meat pies in terms of the cake's price.
We are given that each meat pie costs 1/6 as much as the cake. Let's denote the cost of the cake as C, and the cost of each meat pie as M.
So, we can write the equation:
2M + C = Amount spent
Step 3: Use the information provided to form an equation relating the cost of the cake to the amount spent.
We are told that Victoria spent 5/9 of her money on the cake and the two meat pies. Therefore, the equation can be written as:
5/9 * X = Amount spent
Step 4: Substitute the equations from Step 1 and Step 3 into Step 2.
By substituting the equation from Step 1 into the equation from Step 2, we get:
2M + C = 5/9 * X - $24
Step 5: Substitute the equation from Step 4 and solve for C.
By substituting the equation from Step 4 into the equation from Step 5, we get:
2M + C = 5/9 * (Amount spent) - $24
2M + C = 5/9 * (2M + C) - $24
Now, let's solve for C:
2M + C = (10M + 5C)/9 - $24
18M + 9C = 10M + 5C - $216 (multiplied both sides by 9 to eliminate fractions)
8M + 4C = -$216 (subtracted 10M and 5C from both sides)
Step 6: Solve for the cost of the cake (C).
We have the equation 8M + 4C = -$216. However, we need more information to find the exact values of M and C. The given information does not provide enough details to determine the individual values of M and C.
Therefore, we cannot calculate the exact amount Victoria spent (Question A) or the cost of the cake (Question B) without additional information.
Melody had 98 stickers she gave 2 7 of them to her sister and 3 5 of the remainder to her brother if she wanted to increase her collection of stickers to twice of what she had originally how many more stickers must melody buy?
According to the information given:
Step 1: Determine the fraction of stickers Melody gave to her sister.
Melody gave away 2/7 of her stickers to her sister.
Step 2: Determine the fraction of the remaining stickers Melody gave to her brother.
Melody gave away 3/5 of the remainder to her brother.
Step 3: Calculate the number of stickers Melody gave to her sister.
To find the number of stickers Melody gave to her sister, we need to multiply the fraction (2/7) by the total number of stickers Melody had.
Number of stickers given to sister = (2/7) * 98 = 28
Step 4: Calculate the remaining stickers after giving some to her sister.
To find the number of stickers Melody had remaining after giving some to her sister, we need to subtract the amount given to her sister from the total number of stickers.
Remaining stickers = Total stickers - Stickers given to sister = 98 - 28 = 70
Step 5: Calculate the number of stickers Melody gave to her brother.
To find the number of stickers Melody gave to her brother, we need to multiply the fraction (3/5) by the number of remaining stickers.
Number of stickers given to brother = (3/5) * 70 = 42
Step 6: Calculate the final number of stickers Melody had.
To find the final number of stickers Melody had, we subtract the number of stickers given to her brother from the remaining stickers.
Final number of stickers = Remaining stickers - Stickers given to brother = 70 - 42 = 28
Step 7: Calculate the number of stickers Melody needs to buy to double the initial amount.
To double the initial number of stickers, Melody needs to have 2 times the number she initially had. Since she initially had 98 stickers, the number of stickers she needs to buy is:
Number of stickers to buy = (2 * 98) - Final number of stickers = 196 - 28 = 168
Therefore, Melody needs to buy 168 more stickers to have twice the initial number she had.
