The problem says, "nickels, dimes, and quarters"; all plural, hence there must be at least 2 of any of them.
If there are 2 quarters, then there are 5 dimes making $1.00, so there are 20 nickels.
If there are 3 quarters, then there are 6 dimes making $1.35, so there are 13 nickels.
If there are 4 quarters, then there are 7 dimes making $1.70, so there are 6 nickels.
If there are 5 quarters, then there are 8 dimes making $2.05 -- oops! Too much.
Hence there are exactly three possibliities, 2, 3, or 4 quarters and the resulting number of dimes and nickels.
