Suppose that a company's daily sales volume attributed to an advertising campaign is given by the following equation.
8
64
S(t) =
+ 3
t + 2
(t + 2)2
(a) Find how long it will be before sales volume is maximized.
t =
days
(b) Find how long it will be before the rate of change of sales volume is minimized. That is, find the point of diminishing returns.
days

The answer is 270 cars.you can do this by making a proportional relationship. for instance, 200 is the whole we are using, so on a “number line” 200 would be over 100%. now, since he sells 35% more, add 35% to 100% to get 135% on the other side of the “number line” on the bottom half, leaving the top half empty.cross multiply 200 by 135 then divide by 100 to get your answer. i hope this , if it did, , if you don’t mind, giving me brainiest! 200/100% } 200 • 135 /100 ? /135%
