Daniel has 63 coins which are quarters and dimes in his coin jar. He knows that he has $9.45. How many quarters does he have?

Ans:
Let the number of quarters be x
Then the number of dimes = (63 - x)
Value of x quarters =  cents
Value of (63 - x) dimes =  cents
Total =  cents

i.e.  or 
No. of quarters = 21
No. of dimes = 63 - 21 = 42

Check: Total = 21*25 + 42*10 = 525 + 420 = 945 - correct!
