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 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

Ms. Gartland bought x number of shirts for the new members of her chorus. The cost for x number of shirts, including $3.99 shipping, was $77.49. Each shirt cost $12.25. There was no sales tax on this purchase. Which equation could be used to find x?

• 3.99( x + 12.25) = 77.49

• 3.99x + 12.25 = 77.49

• 12.25(x + 3.99) = 77.49

• 12.25x + 3.99 = 77.49
