The following exercise gives you experience in using the cost and revenue functions to find the break-even point. (See Example 4.)

Austin Avenue Clothiers pays $53 each for sports coats and has a fixed monthly cost of $790. The store sells the coats for $74 each.
(a) What is the linear cost-volume function C(x)?
C(x) = 53x+790
Correct: Your answer is correct.


(b) What is the linear revenue function R(x)?
R(x) = 74x
Correct: Your answer is correct.


(c) What is the break-even number of coats? (Round your answer up to the nearest whole number.)

Respuesta :

Break even number of coats will be 38.

Given in the question,

  • Linear cost value function → C(x) = 53x + 790
  • Linear revenue function → R(x) = 74x

Linear profit function will be,

P(x) = R(x) - C(x)

And condition for the break even point → P(x) = 0

Therefore, P(x) = R(x) - C(x) = 0

By substituting the values of P(x) and R(x),

53x + 790 = 74x

74x - 53x = 790

21x = 790

x = 37.62

x ≈ 38

   Therefore, break even number of coats will be 38.
