Question

Hi,

I need answers for these 2 question as soon as possible because the due date is today.

In the first question, the answer is actually correct, but I do not know how to write it in WebAssign, so if anyone knows that, I will appreciate it.

Simplify each expression below. These are symbolic answers, which must include the letters used as variables. Your answer will be marked as wrong if you use capital letters instead of small letters. If you click the little "eye" icon next to the answer box, a new window will open up to display your answer as if it were printed in a book. This might help you to check whether all of your parentheses are in the right place. (-3x2) (4x7) Cheap Tickets, LLC is promoting tickets by offering a group-discount rate. The regular price is $100 and for each ticket bought the price decreases by $1. (One ticket cost $99, two tickets cost $98, and so on.)

Explanation / Answer

The first answers can be written using the '^' symbols

The answers should be :

-12 x^9

80 t^22

- p^4 / q^18

2) The second part function will be:

Let x = no. of tickets sold,

thus,

Net cost = x * Cost of each ticket

Cost of each ticket = 100 - x

Thus, Net cost = x (100-x)

= 100 x - x2

The revenue is maximum when f'(x) = 0

Thus, f ' (x) = 100 - 2x = 0

x = 50

So, at x = 50 tickets, f(x) = revenue = maximum

Maximum revenue = 50 (100 - 50) = 2500

Note: Both these answers can be directly obtained from the graph as well
