Concept explainers
The bar graphs show U. S. film box-office receipts, in millions of dollars, and box-office admissions, in millions of tickets sold, for five selected years.
Use the information and a calculator to solve exercises 87-88.
88.
a. Use the data displayed by the bar graphs to find the average admission charge for a film ticket in 2000. Round to two decimal places, or to the nearest cent.
b. Use the models to write an algebraic expression that describes the average admission charge for a film ticket x years after 1980.
c. Use the model from part (b) to find the average admission charge for a film ticket in 2000. Round to the nearest cent. Does the model underestimate or overestimate the actual average charge that you found in part (a)? By how much?
d. Can the polynomial division for the model in part (b) be performed using the methods that you learned in this section? Explain your answer.
