dimes --- x
quarters --- 2x - 1
nickels -- 2(2x-1) -1 = 4x - 3
pennies = 5(4x-3) = 20x - 15
10x + 25(2x-1) + 5(4x-3) + 20x-15 = 645
10x + 50x - 25 + 20x - 15 + 20x - 15 = 645
100x = 700
x=7
7 dimes
13 quarters
25 nickels
125 pennies
quarters --- 2x - 1
nickels -- 2(2x-1) -1 = 4x - 3
pennies = 5(4x-3) = 20x - 15
10x + 25(2x-1) + 5(4x-3) + 20x-15 = 645
10x + 50x - 25 + 20x - 15 + 20x - 15 = 645
100x = 700

Samuel's bank has dimes and quarters in it. The number of dimes is four less than three times the number of quarters. If the total value of the coins is $7.85, how many dimes are in the piggy bank?
