    3(10x) + 5x +5(25x)-20x=3600 x=25 1 quarter

    Wouldn't it be 10(x + 3)...etc, cause it says 3 MORE dimes than nickels not sure to add or multiply

    Let x=amount of nickles Then amount of dimes=(x+3) And amount of quarters=(2x-5) We then have 5(x)+10(x+3)+25(2x-5)=360 Solve: 65x=455 x=7 (we have seven nickles) So we have 9 (2*7-5) = 9 quarters
