Clara goes miniature golfing. She pays $7.50 for an admissions ticket and $6.25 for each round she golfs. The total amount Clara pays for admission and the number of rounds she golfs is $26.25.

Which equation can be used to determine the number of rounds, x, that Clara golfs?

• 6.25x + 7.50 = 26.25

• 6.25x - 7.50 = 26.25

• 7.50x + 6.25 = 26.25

• 7.50x - 6.25 = 26.25
