An alpaca rancher would like to show how the size of her herd at the end of year $10$ depends on the abduction rate and the number of annual acquisitions. She would like, for example, to have cell $17$ give the number of year $10$ alpaca if she acquires one animal per year and loses $10\%$ each year. Using the information presented in the spreadsheet below, what formula would be entered in cell G$6?$
