A collection of quarters and nickels is worth $13.70. There are 106 coins in all.

How many of each coin are there?

Answer 1

Nickels + Quarters = 106 ... Quarters= 106 - Nickels

.05Nickels + .25Quarters = 13.70
.05Nickels + .25(106 -Nickels) = 13.70
.05Nickels + 26.5 - .25Nickels = 13.70
26.5 -13.7 = .25Nickels -.05Nickels
12.8 = .2Nickels divide both sides bQuarters .2
64 = Nickels
106 -64 = 42 (Quarters)
