Answer 1

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

\[ \text{Cost} = 1.25p + 2.50n \]

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

\[ \text{Cost} = 1.25(10) + 2.50(30) \]

Calculating each term:

\[ 1.25(10) = 12.50 \]

\[ 2.50(30) = 75.00 \]

Now, adding these together:

\[ \text{Cost} = 12.50 + 75.00 = 87.50 \]

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