Question

A collection of 24 coins, consisting of nickels, dimes, and quarters, has a value of $3.40. if there are twice as many quarters as nickels, and one-third as many nickels as dimes, how many coins of each kind are there?

Answer 1

There would be 8 quarters, 12 dimes, and 4 nickels.
8x.25=2
12x.1=1.2
4x.05=.2
2+1.2+.2=3.4
