This modeled by 1.25 p + 2.50 evluate p = 10 and n = 30 to find how much it will cost Mr. Imani purchase 10 packs of paper and 30 notebooks.

$62.50

$43.75

$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 use the following equation based on the prices given:

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

Where:
- \( p = 10 \) (packs of paper)
- \( n = 30 \) (notebooks)

Now, substituting the values into the equation:

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

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 those two results together to get the total cost:

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

Thus, the total cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks is **$87.50**. Therefore, the correct answer is:

**$87.50**
