In 2010 the average price of a moive ticket was $7.89.Since the the price has increased by an average of 0.15 per year. Write a linear eaquation to represent cost C of a movie ticket y years after 2010.

C = 7.89 + 0.15y

Step-by-step explanation:

The initial price of the ticket = $7.89

Number of years = y

The cost of the ticket after y years = C

Hence, The linear equation =

C = $7.89 + $0.15 × y

C = 7.89 + 0.15y

x is the total time in minutes for the free response

you are given number of questions as 15 - m and time per item as 8 minutes

to find x multiply the two givens together:

x = 8 * (15-m) = 8(15-m)
