A paint store sells 270 pails of paint per month at a price of $32 each. A customer survey indicates that for each $1.20 decrease in price, sales will increase by 6 pails of paint. What is the demand function?

OpenStudy (stormswan):

86-0.2x. I am pretty sure

OpenStudy (anonymous):

yes that is the right answer, but can you please explain how you got it ?

OpenStudy (stormswan):

N = 270 + 6(x/1.2), where N is the number sold and x is the decrease in price.

OpenStudy (stormswan):

do you get that?

OpenStudy (anonymous):
