Question 403739: Use the five steps for problem solving to answer the following question. Show all work and solve.
Laura found $2.15 in quarters and nickles in the bottom of her purse. There were seven fewer quarters than nickles. How many nickles and quarters did she have? Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! nickels-------x
quarters--------x-7
total $ 2.15 = 215 cents
...
5x+25(x-7)=215
5x+25x-175=215
30x=215+175
30x=390
/30
x=13=====> nickels
13-7 = 6 =====> quarters
