To find the total cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks, we use the equation given:

\[ 1.25p + 2.50n \]

Substituting \( p = 10 \) and \( n = 30 \):

\[ 1.25(10) + 2.50(30) \]

Calculating this step-by-step:

  1. Calculate the cost for paper: \[ 1.25 \times 10 = 12.50 \]

  2. Calculate the cost for notebooks: \[ 2.50 \times 30 = 75.00 \]

  3. Add the two costs together: \[ 12.50 + 75.00 = 87.50 \]

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