Question

The average movie ticket price in dollars since 1980 can be modeled by 0.142x + 1.93 where x is the number of years since 1980. What values of x would you use to find the average movie ticket price in 1985, 1999, and 2010? Find the ticket prices for each of those years rounded to the nearest cent.

Answer 1

Explanation:

1985:

x = 5 years ( 1980 to 1985- 5 years)

0.142x + 1.93 = 0.142*5 + 1.93

= 0.71 + 1.93

= $ 2.64

1999:

x = 19 years

0.142x + 1.93 = 0.142*19+ 1.93

= 2.698 + 1.93

=4.628 = $ 4.63

2010:

x = 30 years

0.142x + 1.93 = 0.142*30 + 1.93

= 4.26 + 1.93

= $ 6.19
