The document discusses an item that was sold for $255 in 1979 and $401 in 1985. It asks to find the exponential growth rate k, assuming the value V grew exponentially from the original value of Vo = $255. To solve for k, the formula for exponential growth is used along with the given values for Vo, the initial year, and V, the final year.

1. A doll sold for $255 in 1979 and was sold again in 1985 for $401. Assume that the growth in the
value V of the collector's item was exponential. a) Find the N k of the exponential growth rate.
Assume Vo = 255. K = (Round to the nearest thousandth.)
Solution
LET BASE YEAR BE 1979
