Question 490974: Using q for the variable, write an equation that describes the given situation then solve the equation. The value of q quarters and q-1 nickels is $3.25. Answer by ankor@dixie-net.com(22740) (Show Source):
You can put this solution on YOUR website! Using q for the variable, write an equation that describes the given situation then solve the equation. The value of q quarters and q-1 nickels is $3.25.
:
.25q + .05(q-1) = 3.25
.25q + .05q - .05 = 3.25
.30q = 3.25 + .05
.30q = 3.30
q =
q = 11 quarters
then obviously
11- 1 = 10 nickels

:
Check that;
.25(11) + .05(10) =
2.75 + .50 = 3.25
