Answer:
(a)
(b)P'(5)=-($4.54) Thousand
(c)P'(11)=-($2.10) Thousand
(d)The fifth Month
Step-by-step explanation:
Given the monthly profit model:

(a)We want to derive a model that gives the Marginal Profit, P' of the book.
We differentiate
using quotient rule.

Simplifying

We have derived a model for the marginal profit.
(b) After 5 months, at t=5
Marginal Profit=P'(5)


=-($4.54) Thousand of dollars
(c)Marginal Profit 11 Months after book release

=-($2.10) Thousand of dollars
(d) Since the marginal profit at t=5 is negative, after the 5th Month, the profit starts to experience a steady decrease.
I have to assume that the 24, the 72, and the 18 are feet.
If those are the dimensions of a rectangular prism, like a box, a crate,
or a humongous block of ice, then
Volume = (length) x (width) x (height) =
(24-ft) x (72-ft) x (18-ft) = <em>31,104 cubic ft</em>
If those numbers are <u>inches</u>, then here's the easy way to handle it:
24 inches = 2 ft
72 inches = 6 ft
18 inches = 1.5 ft
Volume = (length) x (width) x (height) =
(2ft) x (6ft) x (1.5ft) = <em>18 cubic feet
</em>
3/4% × 75
3/4 of a percent is .0075.
0.0075 times 75 = 0.5625
The answer is B) 0.5625.
