Freon Production The production of ozone-layer-damaging Freon 22 (chlorodifluoromethane) in developing countries rose from 200 tons in 2004 to a projected 590 tons in 2010.16
a. Use this information to find both a linear model and an exponential model for the amount F of Freon 22 (in tons) as a function of time t in years since 2000. (Round all coefficients to three significant digits.) [HINT: See Example 2.] Which of these models would you judge to be more appropriate to the data shown below?
Year t(years since 2000) | 0 | 2 | 4 | 6 | 8 | 10 |
Amount of Freon 22 F (tons) | 100 | 140 | 200 | 270 | 400 | 590 |
b. Use the better of the two models from part (a) to predict the 2008 figure, and compare it with the projected figure above.
