Answer 1

To find out how much Mr. Imani will spend, we can plug in the values for \( p \) (packs of paper) and \( n \) (notebooks) into the expression \( 1.25p + 2.50n \).

1. Substitute \( p = 10 \) and \( n = 30 \) into the equation: \[ 1.25(10) + 2.50(30) \]

2. Calculate each term:

   • \( 1.25 \times 10 = 12.50 \)
   • \( 2.50 \times 30 = 75.00 \)

3. Now, add these two results together: \[ 12.50 + 75.00 = 87.50 \]

Thus, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.

Therefore, the correct answer is: $87.50
