SHE HAS 24 COINS MADE OF DIMES. HOW MANY OF EACH TYPE OF COIN DOES SHE HAVE? ? # COINS ? VALUE-= T. VALUE

Explanation / Answer

3.75 dollars
24 coins, quarters and dimes

q quarters
So, 24 - q dimes

Value of q quarters is : 25*q = 25q cents
And value of (24 - q) dimes is worth : 10(24 - q) cents

Total is 375 cents

25q + 10(24 - q) = 375

25q + 240 - 10q = 375

15q = 135

q = 9

And thus 24 - q is : 15

So, we have :
9 quarters
15 dimes
