Question

Veronica has $5.25 in quarters and nickles in her car. The number of nickles is three more than the number of quarters. How many of each type of coin does she have?

Answer 1

N=3 +Q

5N+25Q =525

5(3+Q)+ 25Q =525

30Q = 525-15=510

Q=510/30 = 17 Quarters

N= 20 Nickels

.05(20) + .25(17) = 1+4.25 =5.25
