A paint company has a specific type of interior paint which costs $5.55 to produce each unit. The company also has a fixed cost
Maurinko [17]

Answer:

Minimum total cost = $20550

maximum revenue $44,100

Step-by-step explanation:

Given data:

Production cost $5.55 per unit

Fixed cost = $15000 per month

Price, p = 42-0.01 q

where. q represent number of unit produced

revenue can be wriiten as

p.q =  42q - 0.01q^2

1) from information 1000 unit has to produced therefore

total cost = 15000 + 5.55×1000 = $20550

Minimum total cost = $20550

2) Revenue  =  42q - 0.01q^2

\frac{d revenue}{dq} = 42q - 2\times 0.01q = 0

therefore  for maximum revenue q is = 2100

so, maximum revenue =  4.2 \times 2100 - 0.01(2100)^2

                                      =  $44,100
