The profit function given the cost function as 45x + 300 and revenue function as 85x - 0.5x² is - 0.5x² + 40x + 300
How to find profit function
- Revenue function = 85x - 0.5x²
- Cost function = 45x + 300
Profit = Revenue - Cost
= 85x - 0.5x² - 45x + 300
= - 0.5x² + 85x - 45x + 300
= - 0.5x² + 40x + 300
Therefore, the profit function is - 0.5x² + 40x + 300
