Suppose that the weekly sales volume y (in thousands of units sold) depends on the price per unit (in dollars) of the product according to the following formula.

y = 31(3p + 1)−2/5, p > 0

(a) what is the rate of change in sales volume when the price is $23? (round your answer to three decimal places.)

dy
dp
=?

(b) interpret your answer to part (a). (round your answer to the nearest whole number.)

if the price increases $1, the sales volume will decrease by ?

step-by-step explanation:

let

we know that

the y-intercept is the y-coordinate of the point when the value of x is equal to zero

so

the y-coordinate of the point a is the y-intercept

the answer part a) is

the value of y-intercept is

part b) find the slope m

we know that

the value of the slope is equal to

substitute the values

therefore

the answer part b) is

the value of the slope is equal to

the general answer is

the slope is

the value of y-intercept is

the answer is 54 sq. ft. i just did this question, on odyssey ware, and it was right. make brainliest.

answer is 17
