Answer 1

To evaluate the cost for Mr. Imani, we can substitute the values of \( p \) (packs of paper) and \( n \) (notebooks) into the equation \( 1.25p + 2.50n \).

Given:

• \( p = 10 \)
• \( n = 30 \)

Now, substitute these values into the equation: \[ 1.25(10) + 2.50(30) \]

Calculating each part:

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

Now, add these amounts together: \[ 12.50 + 75.00 = 87.50 \]

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

The correct response is: \[ \text{$87.50} \]
