Annual sales for a fast food restaurant are $650,000 and are increasing at a rate of 4% per year. Use an exponential function to find the annual sales after 7 years.

Answer 1

Hi Victoria,

I'd suggest using the following formula for exponential growth:

Where a is your initial amount, r is your growth rate, and x is your number of time intervals. You have everything you need to plug in the numbers and solve for your final annual sales.

Hope it helps!
