Acompany has determined that the demand function for a certain couch is given by p=4000 -0.25x.
where p is the price per couch and x is the number of couches sold. the fixed costs associated with
producing a line of couches is $500.000, and each couch costs $280 to make.
find a function to represent the revenue

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get

"exterior angles = 360 / number of sides.

60 = 360 / sides

sides = 360 / 60

sides = 6"

i believe a. 12x≥120 is the answer
