I got to my answer by just being intuitive. Meaning I just thought about it and even counted on my fingers lol. Then I got my answer.
It can be solved with algebra. Number of quarters = q and number of dimes = d. We have, from the question:
d = q+5 (there are five more dimes than quarters), and
10d + 25q = 330 (total amount of money = $3.30, or 330 cents)
Putting them together:
10(q+5) +25q = 330
35q + 50 = 330
35q = 280
Therefore q=8, and d=13, as stated above.
