Mr. Imani wants to purchase paper and notebooks for his classroom. At Dollar Discount he can buy packs of paper, p, for $1.25 each and notebooks, n, for $2.50 each. This is modeled by 1.25p + 2.50n. Evaluate for p = 10 and n=30 to find how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks. (1 point)

To find the cost, substitute p = 10 and n = 30 into the expression 1.25p + 2.50n:
1.25(10) + 2.50(30) = $43.75 + $75 = $118.75.
Therefore, the correct answer is $43.75.
To find the cost of purchasing 10 packs of paper and 30 notebooks, you need to substitute p = 10 and n = 30 into the equation 1.25p + 2.50n.
Calculating:
1.25 * 10 + 2.50 * 30
= 12.50 + 75.00
= 87.50
Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
To find out how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks, we are given the equation 1.25p + 2.50n, where p represents the number of packs of paper and n represents the number of notebooks.
Substituting p = 10 and n = 30 into the equation, we have:
1.25(10) + 2.50(30)
Evaluating this expression will give us the answer.
1.25(10) = 12.5
2.50(30) = 75
Adding these together:
12.5 + 75 = 87.5
Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
So the correct answer is $87.50.
