Lizzy: John's piggy bank contains quarters, dimes, and nickels. He has three more dimes than quarters and 6 fewer nickels than quarters. If he has 63 coins, how many quarters does John have?.
Me: Hmmm, let me think. I think this is the detailed solution:
Let x represent the number of quarters John has. Nickels: x - 6. Dimes: x + 3. Total:x + x - 6 + x + 3 = 63. 3x - 3 = 63. 3x = 66. x = 22 quarters. Final answer: 22.
