Step-by-step explanation:
a. The revenue function.
The revenue function will be:
= 90 × x
= 90x
b. Profit function
This will be:
= Revenue - Cost
= 90x - (1500 + 10x + 0.2x²)
= 90x - 1500 - 10x - 0.2x²
= 90x - 10x - 1500 - 0.2x²
= 80x - 1500 - 0.2x²
c. The number of Jerseys that Gymnast Clothing manufacture to make a profit
80x - 1500 - 0.2x²
0.2x² - 80x + 1500 = 0
Solving using almighty formula, x will be 20. Therefore, 20 jerseys need to be produced to make a profit.
