Answer:
x = 5
When you sell 5 units, the revenue and the production cost would be equal.
Explanation:
Given
C represents the cost in dollars
R represents the revenue in dollars
To determine
What is the break-even point?
Break-even point:
We know that the cost gets equal to revenue at the break-even point.
i.e.
substitute C=15x+150 and R=45x
divide both sides by 30
Therefore, when you sell 5 units, the revenue and the production cost would be equal.
