What is the value of x?

15 sqrt 3
15 over 2
5 sqrt 3
15 sqrt 2 over 2

1.  (r - c) (3)  =   r(3)  - c(3)  =

r(3)  =  (3)^2+5(3)+14   = 38

c(3) =  (3)^2−3(3)+4  =    4

So   r(3)  - c(3)   =   38  - 4   =    34

The store makes a profit of $3400 in the third month of business

2.  (p * c) (2)   =  p(2) * c(2)  =

p(2)  = 100−2(2)   =  96

c(2)  = 50+5(2)  =  60

So

p(2) * c(2)   =   96 * 60  =  $5760  when the price per customer  = $60
