Tickets are on sale for a basketball game. Each ticket sells for $74.50. Bus shuttle prices to the event cost $15 per family.

Which equation can be used to determine t, the total cost to attend the game if n tickets are purchased by the Gonzalez family?

• n = 74.50t + 15

• t = 15n + 74.50

• t = 74.50n + 15

• t = 74.50n + 15n
