Answer: 22,000 * 1.25^ x
Step-by-step explanation:
The number of pages grows at 25% every week. This number is based on the previous week's number of pages so the increase in page number is being compounded.
Use the future value equation to determine the number of pages after x weeks.
FV = Amount * ( 1 + rate of increase) ^ time
= 22,000 * ( 1 + 25%) ^ x
= 22,000 * 1.25^x
