Final answer:
To determine the break-even point, the equation 1200 + 120x = 200x can be solved. The break-even point occurs when the store is open for 15 hours per month.
Step-by-step explanation:
To determine the break-even point, we need to find the number of hours per month the store needs to be open to cover its expenses.
The expenses consist of the monthly rent of $1,200 and the employee salary of $120 per hour.
The revenue per hour is $200.
To determine the break-even point, we need to find the number of hours 'x' that satisfies the equation:
1200 + 120x = 200x
Solving the equation:
Subtract 120x from both sides: 1200 = 80x
Divide both sides by 80: x = 15
The break-even point occurs when the store is open for 15 hours per month.
