The average price of a movie ticket in 1990 was $4.22 since then the price has increased by approximately 3.1% each year write an exponential function to model this situation then find the price of a ticket in 2016

the price of a ticket in 2016 is $9.33

Step-by-step explanation:

The formula for exponential growth which is expressed as

A = P(1 + r)^t

Where

A represents the average price of a movie ticket after t years.

t represents the number of years.

P represents the initial average price of a movie ticket.

r represents rate at which the price increased.

From the information given,

P = 4.22

r = 3.1% = 3.1/100 = 0.031

The exponential function to model this situation is

A = 4.22(1 + 0.031)^t

A = 4.22(1.031)^t

To find the price of a ticket in 2016,

t = 2016 - 1990 = 26

A = 4.22(1.031)^26

A = $9.33

b is 38 degrees.

a is 52 degrees.

this is because if b is 38 and a is 14 degrees more than b than 38+14=52 and 52+38=90 degrees. hope this .

i think is g(1)=-1.

hope that i can
