Conor is going to the movie theater. A ticket to a movie costs t dollars, and there is a
15% amusement tax on each ticket.
a. Conor buys a ticket to see a movie. Write two expressions in terms of t
showing his total cost.
b. Choose a value for t greater than $12 and less than $13. Use one of the
expressions you wrote in part a to find Conor’s total cost, rounded to the
nearest cent.
a. The two expressions in terms of t showing Conor's total cost are:
1) Total cost without tax: t
2) Total cost with tax: t + 0.15t = 1.15t
b. Let's choose t = $12.50. Using the expression from part a, we can find Conor's total cost with tax:
Total cost with tax = 1.15 * $12.50 = $14.375
Rounding to the nearest cent, Conor's total cost is $14.38.
