Question 1189811
A woman has 25 coins in her pocket, all of which are dimes and quarters. If the total value of the coins is $ 4.75, how many dimes and how many quarters does she have?
---------------
If it were all dimes, it would be 250 cents.
Each dime replaced by a quarter adds 15 cents.

475 - 250 = 225
225/15 = 15 quarters.
