Terra is a fictitious country. The population of Terra was 6 million in the year 2000 and is growing at a rate of 2% per year. The population, P, in millions, as a function of time, t, in years, can be modelled by the function $P(t)=6(1.02)^{t}$. Terra’s government has put in place economic plans such that food production is projected to follow the equation F(t) = 8 + 0.04t, where F is the amount of food that can sustain the population for 1 year. a) Graph P(t) and F(t) on the same set of axes and describe their trends. b) Graph the function y = F(t) - P(t), and describe the trend. Does the Terrian nation currently enjoy a food surplus or suffer from a food shortage? Explain. What about in the years to come? c) Identify the coordinates of the maximum of y = F(t) - P(t) and explain what they mean.

(Test-Drive: Carbon Footprint Calculator) Some scientists believe that carbon emissions, especially from the burning of fossil fuels, contribute significantly to global warming and that this can be combatted if individuals take steps to limit their use of carbon-based fuels. Organizations and individuals are increasingly concerned about their “carbon footprints.” Websites such as Terra Pass

and Carbon Footprint

provide carbon footprint calculators. Test-drive these calculators to estimate your carbon footprint. Exercises in later chapters will ask you to program your own carbon footprint calculator. To prepare for this, use the web to research the formulas for calculating carbon footprints.

At the beginning of 2018 , Terra Lumber Company purchased a timber tract from Boise Cantor for $\$ 3,200,000$. After the timber is cleared, the land will have a residual value of $\$ 600,000$. Roads to enable logging operations were constructed and completed on March 30, 2018. The cost of the roads, which have no residual value and no alternative use after the tract is cleared, was $\$ 240,000$. During 2018, Terra logged 500,000 of the estimated five million board feet of timber. Required: Calculate the 2018 depletion of the timber tract and depreciation of the logging roads assuming the units-of-production method is used for both assets.
