A toy tractor sold for ​$281in 1977 and was sold again in 1989 for $414. Assume that the growth in the value V of the​ collector's item was exponential.

Find the value k of the exponential growth rate. Assume Vo = 281.


k = ????


(Round to the nearest​ thousandth.)


Find the exponential growth function in terms of​ t, where t is the number of years since 1977.


​V(t) =??????


​Estimate the value of the toy tractor in 2006.

$ ?????


​(Round to the nearest​ dollar.)

What is the doubling time for the value of the toy tractor to the nearest tenth of a​ year?


????? years


​(Round to the nearest​ tenth.)

Find the amount of time after which the value of the toy tractor will be ​$956.


???? years



​(Round to the nearest​ tenth.)
