Answer 2

To evaluate the expression 1.25p + 2.50n, substitute p=10 and n=30:

1.25(10) + 2.50(30) = 12.50 + 75 = $87.50

Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.

Answer 3

Apologies for the mistake. Let's redo the calculation.

1.25p + 2.50n

Replacing p = 10 and n = 30:

1.25(10) + 2.50(30) = 12.50 + 75 = $87.50

Therefore, it will cost Mr. Imani $87.50 to purchase 10 packs of paper and 30 notebooks.
