Question 1047707: Robin has a collection of nickels, dimes, and quarters worth $50.50. She has 30 more coins than nickels and twice as many quarters as dimes. How many coins of each does she have? Answer by jorel555(1290) (Show Source):
You can put this solution on YOUR website! Let n represent nickels. Then dimes are n+30; and quarters are 2n+60. So:
5n+10(n+30)+25(2n+60)=5050
65n+1800=5050
65n=3250
n=50
She has 50 nickels, 80 dimes, and 160 quarters. ☺☺☺☺
