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, Mr. Imani has to multiply the price of the paper, $1.25, by the number of packs he wants to buy, 10, and multiply the price of the notebooks, $2.50, by the number of notebooks he wants to buy, 30. Then, he has to add the two results together:
Cost = (1.25 * 10) + (2.50 * 30)
Cost = $12.50 + $75.00
Cost = $87.50
Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
To evaluate the cost, we substitute the values of p and n into the expression 1.25p + 2.50n.
Given p = 10 and n = 30,
Cost = 1.25 * 10 + 2.50 * 30
Calculating,
Cost = 12.50 + 75
Cost = 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 can substitute the given values of p and n into the expression 1.25p + 2.50n.
Given:
p = 10
n = 30
Substituting the values, we get:
1.25(10) + 2.50(30)
Evaluating this expression, we first multiply:
12.50 + 75.00
And then add:
$87.50
Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
The correct answer is: $87.50
