The sales for exercise equipment in a country were $1824 million in 1990 and $5832 million in 2005. (a) Use the regression feature of a graphing utility to find an exponential growth model and a linear model for the data. (Use y to represent sales in millions of dollars and t to represent years after 1990. Enter your values to 4 decimal places.) y = (exponential model) y = (linear model) (b) Use the exponential growth model to estimate the sales in 2014. (Enter your answer to 1 decimal place.) $ million (c) Use the linear model to estimate the sales in 2014. (Enter your answer to 1 decimal place.) $ million (d) Use a graphing utility to graph the models from part (a). Which model is more accurate? The exponential model is more accurate. The linear model is more accurate. More information is needed.

(a) Find an exponential model of the form
f(t)equals=y0bt
for these data, where
tequals=0
corresponds to the year 2000. If you do not have suitable
technology, use the first and last data points to find a function.
If you have a graphing calculator or other suitable technology,
use exponential regression to find a function.
