A nickel is 5 cents each and n=nickel so 5n is a nickel, and a penny is 1 cent each so p=penny so 1p is a nickel then you plug them in and get:

5 (8) and 1 (12) and that = 52 cents

The answer is 52 cents

Nickel = $0.05

pennies = $0.01

(0.05 x 8) + (0.01 x 12) =

0.40 + 0.12 = 0.52

$0.52 or 52 cents
