Suppose that each day a company has fixed costs of 400 dollars and variable costs of 0.8x+1420 dollars per unit, where x is the
Bess [88]

Answer:

Step-by-step explanation:

Given that a company fixed costs are 400 dollars

and variable cost = 0.8x+1420 per unit and x the no of units produced

Selling price = 1500-0.25x per unit

a) Break even units

At break even units selling price = variable cost

1500-0.25x=0.8x+1420\\1.05x = 80\\x=76.19~76

Break even units = 76

b) Revenue = Sales - total costs

= x(1500-0.25x)-(x)(0.8x+1420)-400\\= 1500x-0.25x^2-0.8x^2-1420x-400\\= -1.05x^2+80x-400

Use derivative test to get max revenue

R'(x) = -2.10x+80

R"(X) <0

So maximum when I derivative =0 or when

x=38.10

x=38

c) price when x =38 is

P = 1500-0.25(38)\\=1490.5
