Sorry I know it’s long but I need help Jackie is selling smoothies at a school fair. She starts the day with $15 in her cash box to provide change to her customers. If each smoothie costs $3.75, which graph represents the balance of the cash box, y, after Jackie sells x smoothies?
A.
A graph plots the number of smoothies sold versus the balance of the cash box. A diagonal curve rises through (0, 0), (1, 15), (2, 30) and (4, 60) on the x y coordinate plane.
B.
A graph plots the number of smoothies sold versus the balance of the cash box. A diagonal curve rises through (0, 15), (2, 22 point 5), (4, 30), (6, 37 point 5), (8, 45), (10, 52 point 5), (12, 60), (14, 67 point 5) and (16, 75).
C.
