Ashton needs a total of $1.50 in quarters for a coin operated car wash. He already has $0.75. Which equation can be used to find q, the number of additional quarters Ashton needs in order to have enough money for the car wash?

• 1.5 = 0.75q + 0.25

• 0.75 = 1.5q + 0.25

• 0.75 = 0.25q + 1.5

• 1.5 = 0.25q + 0.75
