A toy tractor sold for $203 in 1977 and was sold again in 1989 for $ 466. 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 Vo=203
b. ) Find the exponential growth function in terms of t, where t is the number of years since 1977
c. ) Estimate the value of the toy tractor in 2015
d. ) What is the doubling time for the value of the toy tractor to the nearest tenth of a year?
e. ) Find the amount of time after which the value of the toy tractor will be $2931.
