Answer 1

To find the cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks, we can plug in the values for \( p \) and \( n \) into the cost equation:

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

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

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

Calculating each part:

1. \( 1.25(10) = 12.50 \)
2. \( 2.50(30) = 75.00 \)

Now, add the two amounts together:

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

Therefore, the total cost is $87.50.
