Answer: 14 dimes and 8 quarters
Step-by-step explanation:
dimes ($0.10): x + 6
quarters ($0.25): x
Cost*quantity of dimes + Cost*quantity of quarters = Total value
0.10(x + 6) + x(0.25) = 3.40
0.10x + 0.60 + 0.25x = 3.40
0.35x + 0.60 = 3.40
-0.60 -0.60
0.35x = 2.80
÷0.35 ÷0.35
x = 8
dimes: x + 6 = 8 + 6 = 14
