Question 428023: Mary has $2.15 in change consisting of 11 more dimes than nickels. Find the number of nickels and dimes. how do you set up this problem and solve it? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Assuming Mary has only nickels and dimes,then:
nickels=x
dimes=x+11
5x+10(x+11)=215
15x+110=215
15x=105
x=7
x+11=18
Mary has 7 nickels, and 18 dimes..
