Motor Vehicle Ownership World motor vehicle ownership in developing countries and Eastern Europe can be modeled by the function

M(t) = 6.25t + 50

where t is the number of years since 1970 and M(t) is in millions of vehicles (World Resources Institute, www.wri.org). Graph this function. What is the expected average rate of change of motor vehicle ownership from 1990 through 2010?

Is motor vehicle ownership expected to grow faster in developed or developing countries in the period 1990 through 2010? (See the exercise.)

Motor Vehicle Ownership World motor vehicle ownership in developed countries can be modeled by the function

where t is the number of years since 1970 and M(t) is the number of motor vehicles in millions in the year 1970 + / (World Resources Institute, www.wri.org). See the accompanying figure. How many vehicles were there in developed countries in 1988? How many will there be in 2010? What was the average rate of change of motor vehicle ownership from 1984 to 1994?
