Question

please help..
how to solve this problem?

When x units of a certain luxury commodity are produced, they can all be sold at a price of p thousand dollars per unit, where p=-6x+100.
A. Express the revenue R(x) as a function of x.
B. How much revenue is obtained when x=15 units are produced and sold?

Answer 1

Revenue is selling price multiplied by number of units sold.

Answer 2

Selling price is given. Units is x.

Answer 3

how much is the Revenue or the selling price there??

Answer 4

They tell you the selling price in the question... it's p.

Multiply it by x. That gives revenue.

Answer 5

p=-6x+100 ?

Answer 6

Don't solve it. Multiply p, which is -6x+100, by x.

x(-6x+100)

Answer 7

R(x) = x(-6x+100)

Answer 8

Revenue is price per unit (which is -6x+100) multiplied by number of units sold (which is x)

So your revenue is R(x) = x(-6x+100)

Answer 9

Let each unit = x\[1 unit = x \]

Let number of units sold = p\[1000$/unit = p \]
Note* = The money we make is in 1000s of dollars.

Let the Revenue we make be \[x *(p)\]

we know p \[p = -6x +100\]

\[Hence, R = x(p) = x(-6x +100)\]

Answer 10

I'm sure you can at least try to simplify it on your own @phopXD

Answer 11

Agent0 completed part a. just evaluate it at x = 15, multiply the answer by 1000$.

Answer 12

ok..

Answer 13

thanks mebs :)

Answer 14

To evaluate at x = 15

\[R(15) = (15)(-6(15) +100) \]
