1. Assuming that the company sells all that it produces, what is the profit function?
nalin [4]

The  profit function is R(x) = -0.5 (x - 50²) + 1150

  • The domain of P(x)  is:  0 ≤ x ≤ 150
  • Profit when producing 50 items = 1150
  • Profit when producing 60 items =  1100
<h3> What is the profit function about?</h3>

Note that:

1. Profit  = Revenue - cost

P (x) =  0.5 ( x - 90²) + 4050 - 40x - 100  

= 0.5 ( x² - 180 + 8100 + 4050 - 40x - 100  

=0.5 x² - 50x - 100  

=0.5( x² - 100x) - 100  

=  -0.5 (x - 50²) + 1150

2.  Since the minimum unit is 50.

Then   x ≤ 150

X = describe the item so it need to be a negative number

  • x ≥ 0

Hence the domain of P(x)  is:  0 ≤ x ≤ 150

3. Assume x = 50 , 60

R(50) = 1150 , R (60 ) = -0.5 (60-50)² + 1150 = 1100

4. R (x) = -0.5 (x-50)² + 1150  then 50 more unit is removed hence, Profit when producing 60 items =  1100

Therefore, The  profit function is R(x) = -0.5 (x - 50²) + 1150

  • The domain of P(x)  is:  0 ≤ x ≤ 150
  • Profit when producing 50 items = 1150
  • Profit when producing 60 items =  1100

A music store sold 300cds and 100cd players. If each cd cost $12 and each cd player cost $35, what was the store total earnings
Pachacha [2.7K]

So with what we know we can set up two equations to  solve for the CDs and the players.


$12(300) = total earnings for cds

= $3600 total cds sold


$35(100) = total earnings for cd players

=$35000


add both of the totals of the CDs and the CD players to get the total earnings

$3600+$3500 = $7100 gained in total from both products sold
