34 quarters. 6 nickles.
10 Nickels 2 Quarters = $1.00 4 Dimes 7 Nickels 1 Quarter = $1.00 8 Dimes 4 Nickels = $1.00
The idea is to write two equations, one for the number of coins, one for the amount of money. Then solve the equations.Assuming "n" is the number of nickels, and "q" the number of quarters, the equations for the coins, of course, is quite simply: n + q = 64 And the equation for the money (I'll use cents; you can just as well use dollars if you prefer): 5n + 25q = 740 You can solve the first equation for "n", then replace that in the second equation.
