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

To find out how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks, we can substitute the given values of p = 10 and n = 30 into the expression 1.25p + 2.50n and then evaluate it.

So, let's substitute p = 10 and n = 30 into the expression 1.25p + 2.50n:

1.25(10) + 2.50(30)

Multiplying 1.25 by 10 gives us:
12.50 + 2.50(30)

Multiplying 2.50 by 30 gives us:
12.50 + 75

Adding the two values together gives us the final answer:
12.50 + 75 = 87.50

Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
