Question

I need help with my final exam review :P, PLZ

Answer 1

i need help with #13 b

Answer 2

First, remember that revenue is the amount of goods produced times the production cost, i.e., x * p. Then, take the derivative and let it equal to zero to find extrema points.

Answer 3

That will give you the x coordinate. Plug it in the revenue function :-)

Answer 4

so the answer on the review is wrong?

Answer 5

Nope, that's correct. What did you get for the x-coordinate?

Answer 6

50?

Answer 7

The derivative is 50 - 0.1x = 0 -> x = 50/0.1, not 50 :-)

Answer 8
