3-65.

The price of a movie ticket averages $10.25 and is increasing by 3% per year. Use that information to complete parts (a) through (c) below. Homework Help ✎

What is the multiplier in this situation?

Since the price is increasing, the multiplier is 100% + 3%.

1.03

Write a function that represents the cost of a movie ticket

*n*years from now.Use the general equation for an exponential function:

*t*(*n*) =*a*(*b*),^{n}

where*a*is the initial value,*b*is the multiplier, and*n*is time, in years.*t*(*n*) = 10.25(1.03)^{n}If tickets continue to increase at the same rate, what will they cost 10 years from now?

Use the equation from part (b).
