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

Which representation shows a proportional relationship between x and y?
