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.

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm

The answer would be 484
