anonymous · Answer

q = # of quarters
d = # of dimes

.25q + .1d = 1.95

d = 4q since there are 4 times as many dimes as there are quarters.

use substitution:
.25q + .1(4q) = 1.95
.25q + .4q = 1.95
.65q = 1.95
q = 3
so d = 12

L: Let x = # of quarters worth 25 cents each
Let 4x = # of dimes worth 10 cents each

E: 195 cents = 25(x) + 10(4x)

S: 195 = 65x
    3 = x

C: 195 = 25(3) + 10(12)
195 = 75 + 120
195 = 195

A: There are 3 quarters and 12 dimes
