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
Answer:
The width of each bedroom is 12 feet.
Step-by-step explanation:
Each bedroom has 2 walls 13 feet long. That is a total of 8 times 13, which equals 104.
