You can put this solution on YOUR website! Jill found a box of pennies, nickels, dimes and quarters that was worth $7.05. The number of nickels was twice the number of pennies while the number of dimes was three times the number of pennies. If the number of quarters was twice the number of nickels, how many quarters are there in the pile of coins?
pennies -----------x
nickels ----------2x
dimes--------------3x
quarters--------2*2x
x+5*2x+10*3x+25*4x=705
x+10x+30x+100x=705
141x=705
x=705/141
x= 5 pennies
nickels = 2x = 10
dimes = 3x = 15
quarters 4x=4*15=60
