33a. $4.50t$
33b. $40.50
Work Step by Step
33a. The cost of each ticket is 4.50, and the number of tickets sold is represented by $t$ . To find the total cost of $t$ tickets, you need to multiply the price of an individual ticket by the number of tickets sold. $(ticket \ price) \times (tickets\ sold)$
33b. It is given that $n$ tickets cost 36 dollars, and an individual ticket costs 4.50. To find the total cost if one more ticket is purchased, use the equation $36+4.50=40.50$
