Answer 1

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

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

Calculating each term:

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

• For the notebooks: \[ 2.50 \times 30 = 75.00 \]

Now, add the two amounts 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.
