A toy tractor sold for $282 in 1979 and was sold again in 1988 for $492. Assume that the growth in the value V of the collector's item was exponential a) Find the value k of the exponential growth rate. Assume V. = 282. (Round to the nearest thousandth.) b) Find the exponential growth function in terms of t, where t is the number of years since 1979. V(t) = c) Estimate the value of the toy tractor in 2009. (Round to the nearest dollar.) d) What is the doubling time for the value of the toy tractor to the nearest tenth of a year? years
