Answer: The value after 7 years is $ 855355.65 Solution: Given that, Annual sales for a fast food restaurant are 650000 and are increasing at a rate of 4% per year To find: exponential function to find the annual sales after 7 years The exponential growth function is given as: Where, “a” is the initial amount “y” is the future value “r” is the rate of interest in decimal “t” is the number of years Here in this given question, a = 650000 t = 7 years Substituting the values in given formula, Thus the value after 7 years is $ 855355.65 Step-by-step explanation: 1. Annual sales for a fast food restaurant are $ 650,000 and are increasing at a rate of 4% per ve: Write an exponential growth function, then find the annual sales after 7 years. 2.
