Question

anonymous · Answer

Let the number of pennies = number of dimes = n.
n + n + no. of quarters = 47
no. of quarters = 47-2n.

Try using that information and the fact that their total value is $4.73 to figure out what n is, and from there figure out how many pennies, dimes and quarters there are.
