A toy tractor sold for ​$203 in 1977 and was sold again in 1989for $ 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. AssumeVo=203
b. ) Find the exponential growth function in terms of​ t, wheret 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 tractorto the nearest tenth of a​ year?
e. ) Find the amount of time after which the value of the toytractor will be​ $2931.
