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:
-
For the packs of paper: \[ 1.25 \times 10 = 12.50 \]
-
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
