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 evaluate the expression 1.25p + 2.50n, substitute p=10 and n=30:
1.25(10) + 2.50(30) = 12.50 + 75 = $87.50
Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
wrong
Apologies for the mistake. Let's redo the calculation.
1.25p + 2.50n
Replacing p = 10 and n = 30:
1.25(10) + 2.50(30) = 12.50 + 75 = $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 substitute the values of p=10 and n=30 into the expression 1.25p + 2.50n.
Let's calculate it:
1.25(10) + 2.50(30) = 12.50 + 75 = $87.50
Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
To find how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks, we need to substitute the given values of p = 10 and n = 30 into the expression 1.25p + 2.50n.
Plugging in p = 10 and n = 30:
1.25p + 2.50n = 1.25*10 + 2.50*30
Simplifying the expression:
1.25*10 + 2.50*30 = 12.50 + 75
Adding the numbers:
12.50 + 75 = 87.50
Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
Hence, the correct answer is $87.50.
