Could someone ?
the sales s (in thousands of units) of a cleaning solution after x hundred dollars is spent on advertising are given:
s = 10(1 - e^(kx))
now when $325 is spent on advertising 2300 units are sold.
(a)complete by solving for k. (round your answer to 4 decimal places)

(b) what number of units that will be sold if advertising is raised up to $425
