Answer:
667 horse shoes
Explanation:
Given that,
The company's fixed and variable costs are modeled by the function
Cost function: C(x) = 5.6x + 1,200
Revenue function: R(x) = 7.4x
x ⇒ represents the number of horse shoes
For break even,
Cost = Revenue
5.6x + 1,200 = 7.4x
7.4x - 5.6x = 1,200
1.8x = 1,200
x = 667
Therefore, they have to sell 667 horse shoes to break even.
