 Question 158497: A cashier has 2 times as many nickels as quarters, 15 more dimes than quarters that worth \$3.75 in total. Find how many dimes she has.Answer by nerdybill(6948)   (Show Source): You can put this solution on YOUR website! A cashier has 2 times as many nickels as quarters, 15 more dimes than quarters that worth \$3.75 in total. Find how many dimes she has. . Let q = number of quarters then from: "2 times as many nickels as quarters" 2q = number of nickels and from: "15 more dimes than quarters" q+15 = number of dimes . Because the cashier has a total of \$3.75: 3.75 = .25q + .10(q+15) + .05(2q) 3.75 = .25q + .10q + 1.5 + .1q 3.75 = .45q + 1.5 2.25 = .45q 5 = q (number of quarters) . Number of dimes: q+15 = 5+15 = 20 (number of dimes)
