Janet has three times as many dimes as nickels and twice as many quarters as nickels. If she has $3.40 in all, how many nickels, dimes, and quarters does she have?
If n represents the number of nickels Janet has. How do i set up the equation?

Question

anonymous · Answer

d= dimes
n=nickles
q=quarters
d=3n, q=2n
.1d+.05n+.25q=3.4
so input values and get:
.1(3n)+ .05n +.25(2n)=3.4
.3n+.05n+.5n=3.4
.85n=3.4
n=4
d=12
q=8
