Answer:
n = 24
q = 8
Step-by-step explanation:
Let:
n = nickels
q = quarters
5n + 25q = 320
n + q = 32
n = 32 - q
Substitute (to solve for q):
5(32 - q) + 25q = 320
160 - 5q + 25q = 320
160 + 20q = 320
20q = 320 - 160
20q = 160
q = 160 ÷ 20
q = 8
Substitute (to solve for n):
n = 32 - q
n = 32 - (8)
n = 24
