Nickels (0.05): Q + 6
Dimes (0.10): Q + 8
Quarters (0.25): Q
Nickels + Dimes + Quarters = Total
0.05(Q + 6) + 0.10(Q + 8) + 0.25(Q) = 4.70
0.05Q + 0.30 + 0.10Q + 0.80 + 0.25Q = 4.70
0.40Q + 1.10 = 4.70
0.40Q = 3.60
Q = 9
Nickels (0.05): Q + 6 = (9) + 6 = 15
Dimes (0.10): Q + 8 = (9) + 8 = 17
Answer: Nickels = 15, Dimes = 17, Quarters = 9
