Tom, Larry, and Moe met up at Anderson's to get some ice cream, but they only had nickels, dimes and quarters with them. They had two more dimes than twice the number of quarters, and 8 more nickels than quarters. If together they had $6.60, how many quarters, dimes, and nickels do they have?
+1252 Answer: 20 nickels, 26 dimes, 12 quarters
Explanation:
Let n = # of nickels, d = dimes, and q = quarters
d = 2q+2
n = q+8
5n+10d+25q = 660
Simple system of equations, after a couple minutes of solving, you'll get n=20, d = 26, and q = 12. So 20 nickels, 26 dimes, and 12 quarters.
You are very welcome!
