Answer: There are 80 nickels, 120 dimes, and 300 quarters.
Step-by-step explanation:
Since for every 2 dimes there are 5 quarters, and for every 2 nickels there are 3 dimes, there can be 4 nickels, so there will be 6 dimes and 15 quarters. When you add all of them up it equals 25, so you take 500 divided by 25, and that equals 20, so you take the 4 nickels, 6 dimes, and 15 quarters times 20.
20 x 4 = 80
20 x 6 = 120
20 x 15 = 300
