Stella has 63 coins. The coins are a mixture of quarters and dimes. She has a total of $10.80. How many quarters and how many di
nika2105 [10]
Q + d = 63....q = 63 - d
0.25q + 0.10d = 10.80

0.25(63 - d) + 0.10d = 10.80
15.75 - 0.25d + 0.10d = 10.80
-0.25d + 0.10d = 10.80 - 15.75
-0.15d = -4.95
d = -4.95/-0.15
d = 33 <=== 33 dimes

q + d = 63
q + 33 = 63
q = 63 - 33
q = 30 <=== 30 quarters
