Not being American, i assume a dimes is 10 cents and a quarter is 25 cents.
There are 35 coins, so call the number of quarters X and the number of dimes 35 -X
The equation is then 25X + 10(35 - X) = 695 (Do it all in cents)
25X + 350 - 10X = 695
15X = 345
X= 23
So there should be 23 quarters and 12 dimes
Check 23 x 25 + 12 x 10 = 575 + 120 = 695
