You can put this solution on YOUR website! Tina’s bank contains quarters, nickels and dimes. She has three more dimes than quarters and 6 fewer nickels than quarters. If she has 63 coins, write and solve an equation to find how many quarters Tina has.
====================================
d = q + 3
n = q - 6
n + d + q = 63
----------------
Sub for n & d
(q+3) + (q-6) + q = 63
3q - 3 = 63
3q = 66
q = 22 quarters
---
d = 25 dimes
---
n = 16 dimes
