Answer:
There are 12 dimes , 24 quarters and 15 nickels in piggy bank
Step-by-step explanation:
d
q = 2d
n = d + 3
0.1d + 0.25(2d) + 0.05(d + 3) = 7.95
0.1d + 0.5d + 0.05d + 0.15 = 7.95
0.65d = 7.80
d = 12 , q = 24 , n = 15
There are 12 dimes , 24 quarters and 15 nickels in piggy bank
Check the answer:
12(0.1) + 24(0.25) + 15(0.05)= 7.95
7.95 = 7.95
