To determine how much it will cost Mr. Imani to purchase 10 packs of paper and 30 notebooks, we can substitute \( p = 10 \) and \( n = 30 \) into the cost expression \( 1.25p + 2.50n \).

Calculate each component:

  1. Cost of paper: \[ 1.25 \times 10 = 12.50 \]

  2. Cost of notebooks: \[ 2.50 \times 30 = 75.00 \]

Now, add both costs together: \[ 12.50 + 75.00 = 87.50 \]

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

The correct response is: $87.50
