Mary had 15 coins in nickels and quarters. She had 3 more quarters than nickels. Which system of equations represents this situation, letting x represent the number of nickels and y represent the number of quarters?

Question

A x + y = 15 y = 3 – xx + y = 15 y = 3 – x

B x + y = 3 y = 15 + x x + y = 3 y = 15 + x

C x - y = 15 y = 3 + xx - y = 15 y = 3 + x

D x + y = 15 y = 3 + x

Answer 1

The correct answer is:

D) x + y = 15
y = 3 + x

Answer 2
