Question

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) Responses $62.50 $62.50 $43.75 $43.75 $450.00 $450.00 $87.50

Answer 1

To find the total cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks, we can substitute the values of \( p \) and \( n \) into the expression \( 1.25p + 2.50n \).

Given:

• \( p = 10 \)
• \( n = 30 \)

We can calculate the total cost as follows:

\[ \text{Total Cost} = 1.25(10) + 2.50(30) \]

Calculating each part:

1. \( 1.25 \times 10 = 12.50 \)
2. \( 2.50 \times 30 = 75.00 \)

Now, adding these two amounts together:

\[ \text{Total Cost} = 12.50 + 75.00 = 87.50 \]

So, the total cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks is \($87.50\).

The correct response is \( \text{$87.50} \).
