Astore uses the expression -2p + 50 to model the number of backpacks it sells per day, where the price, p, can be anywhere
from $9 to $15. which price gives the store the maximum amount of revenue, and what is the maximum revenue?

The maximum revenue is 32.

p=9 gives the store the maximum revenue

Step-by-step explanation:

Hi, since the term with the variable p is negative (-2p) the maximum revenue is given by the lower price (p).

So, substituting with the lowest price p=9 in the expression:

-2p + 50

-2(9) +50

-18+50

32

The maximum revenue is 32.

p=9 gives the store the maximum revenue

the slope of the line is 60

one point on the line is (40,10)

step-by-step explanation:

in the equation outside the parenthesis the equation always tells you the slope. in this case it is 60.

in the parenthesis is also says 40 which is x because it is near the x and 10 is y because it is near y.
