The formula for estimating the number, N, of a certain product sold is N = 9200ln (5t + 3), where t is the number of years after the product is introduced. What is the expected number of sales 3 years after the product is introduced? Round to the nearest whole number.

A. 44,423

B. 26,591

C. 24,917

D. 24,922

To determine the expected number of sales after 3 years of a product, we need an equation that would relate time with the number of sales. In this case, we use the equation above which expresses the number of sales as a function of time. We simply substitute the time which would be 3 years to the equation and evaluate the value of N. We do as follows:

N = 9200 ln (5t + 3)

N = 9200 ln (5 (3) + 3)

N = 9200 ln 18

N = 26591.42

Therefore, the correct answer would be option B. The number of sales after 3 years would be about 26591.
