Step-by-step explanation
By definition:
• the number of units is x,
,
• the cost function C(x) = 12x + 15,000,
,
• the revenue function R(x) = 32x,
,
• the profit function P(x) = R(x) - C(x).
The break-even point is the point x where we have P(x) = 0. So we must find x such that:
![\begin{gathered} P(x)=R(x)-C(x)=0, \\ 32x-(12x+15,000)=0, \\ 20x-15,000=0, \\ x=(15,000)/(20)=750. \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/hn587gv2orunpu2gj7yu314f3gf93c695k.png)
We have found that the break-even point is x = 750 units.
Answer
750 units
