Answer 1

To find the total cost for Mr. Imani to purchase 10 packs of paper and 30 notebooks, we can substitute \( p = 10 \) and \( n = 30 \) into the expression \( 1.25p + 2.50n \).

Let's calculate:

\[ 1.25p + 2.50n = 1.25(10) + 2.50(30) \]

Calculating each term:

\[ 1.25(10) = 12.50 \] \[ 2.50(30) = 75.00 \]

Now add these two amounts together:

\[ 12.50 + 75.00 = 87.50 \]

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