Chapter A1, Problem 4PE

Example $1.2$ in the chapter described a scenario for new product sales that can be characterized by a formula called a Gompertz curve: $S=a{e}^{b{e}^{ct}}$ Develop a spreadsheet for calculating sales using this formula for $t=0$ to $160$ in increments of $10$ when $a=15,000,b=-8,\text{ and }c=-\mathrm{0.05.}$
