Question

19. Amy has 8 coins worth $1.40. Some of the coins are nickels and some are quarters. How

many of each coin does Amy have?

Answer 1

5 quarters and 3 nickels

Explanation:

x = nickels

y = quarters

x + y = 8

x(0.05) + y(0.25) = 1.40

3 + 5 = 8

3(0.05) + 5(0.25) = 1.40

0.15 + 1.25 = 1.40

1.25 + 0.15 = 1.40
