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.
