im srry, I only have a graphing calc. not sure how to use it compared to the old ti i had.. :( rly srry. i think the equation is 22=(6.5438x10^4)xe^(.47x20) ? i think. Just trying to help.

Answer 16

65,438

population = 65,438 * 1.047^y where y is number of years.

so after 1 year = 65,438 * 1.047^1 = 68,514

After 22 years 65,438 * 1.047^22 = 65,438 * 2.7467997357
equals 179,745
