Answer:
17
Step-by-step explanation:
We can set this up by using an equation where D is the number of dimes and N is the number of nickels.
N x .5 + D x .10 = $2.45
N + D = 32
If we work our way through the equations, we find that D = 32 - N. We can plug this into the first equation and get N(.5) + .10(32-N) = $2.45
If we simplify the equation, we get 3.20-N(.5)=2.45, and thus N, or the number of nickels, equals 15.
If we go to the second equation and plug in N=15, we get 15+D=32. If we subtract 15 from both sides, we get D, or the number of Dimes, equals 17.
