Clara goes miniature golfing. She pays $7.50 for an admission 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
