Keesha has 10 more quarters than dimes, which, together, total $11.25. How many coins does she have in quarters and dimes?
1 answer:
Assume Keesha has d dimes, so she has d + 10 quarters
Total money Keesha has is (d+10)*.25 + d*.1 = 11.25
or 0.35d + 2.5 = 11.25
Solving for d , d = 25
So Keesha has 25 dimes and 35 quarters, total of 60 coins
