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 $87.50 $87.50 $43.75 $43.75 $450.00

Answer 1

To evaluate the cost for Mr. Imani, we'll use the formula:

\[ \text{Total Cost} = 1.25p + 2.50n \]

We are given:

• \( p = 10 \) (packs of paper)
• \( n = 30 \) (notebooks)

Now, substituting the values into the formula:

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

Calculating each part:

1. For the packs of paper: \[ 1.25 \times 10 = 12.50 \]

2. For the notebooks: \[ 2.50 \times 30 = 75.00 \]

Now, add the two amounts together:

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

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