The number of customers at Pumpkin PiBakery depends on the price of the pie. Market research says that the number of customers can be estimated by ()=110−4.4,where p is the price of a pie.

Step-by-step explanation:

To find;

a) The number of customers that will be there if the bakery charges $10 per pie

b) To determine how much money (revenue) the bakery will make at that price if one customer buys only one pie.

So; given the function:

C(p) = 110 - 4.4 p

where

p = 10

C(10) = 110 - 4.4(10)

C(10) = 110 - 44

C(10) = 66

Thus, when the bakery charges $10, the number of customers is 66.

The revenue now when each customer purchase only one pie is:

= $66 × 10

= $660

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
