Suppose that after a company introduces a new product, the number of months before its market share is x percent is given by m = 20 ln(40/40 - x), where x

We have m = 20 ln(40/(40-x) where x < 40 and m is the number of months before the Company’s market share is x %. Thus, when x = 39, we have m = 20ln( 40/40-39) = 20 ln 40 = 20*3.68879454 = 73.77. Thus, the Company’s market share will be 39 % after about 74 months.
