A demand function for a certain product is given by the equation q=2000−70p, where p is the price in dollars, and q is the quantity demanded. 1). Find a function to represents the revenue generated by producing and selling q (not p) items. 2). Define your variables. 3). Use this function to determine the quantity that maximizes revenue. Explain/show how you got the max. 4). What price should be charged in order to maximize revenue?

$8

step-by-step explanation:

it is pretty much backwards.

you take the 4x2 multiply that, and that is = $8

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
