Question 22942: Help. I'm having an Issue with a word problem can anyone help
In 1990 population is 25 million. Exponential growth rate of 1.5% per year. Model by function p(t)=Poe^.015t

, where t=0 in 1990.
The problem is to find p(t) in year 2000 when t=10. In other words, find p(10).
= 29,045,856, using a calculator.
Since the problem is only given to 2 significant digits of accuracy, probably the answer is not more accurate than this. Call it about 30,000,000. I'm not sure what groundrules your instructor or the textbook may have given concerning accuracy of the problem.
