Sal keeps quarters, nicles, and dimes in his change jar. He has a total pf 52 coins. He has three more quarters than dimes and five fewer nicles than dimes. How many dimes does Sal have?
You can try trial and error.
a. 16 quarters, 13 dimes, 8 nickles = 37 coins Nope. That isn't the answer.
Keep going til you find the right answer.
Let x = number of dimes. Since the value of the coins does not matter, the quarters = x + 3, dimes = x and nickels = x-5.
(x + 3) + x + (x - 5) = 52
Solve for x.
I hope this helps. Thanks for asking.
