Question

Keesha has 10 more quarters than dimes, which, together, total $11.25. How many coins does she have in quarters and dimes?​

Answer 1

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
