suppose you are starting an office-clening service. You have spent $315 on equipment.To clean an office, you use $4 worth of supplies.Yoou charge $25 per office. How many offices must you clean to break even?

15

To determine how many offices you must clean to break even, you need to calculate the total cost and the revenue generated per office.

Let's break down the costs:

1. Equipment cost: You have spent $315 on equipment.
2. Supplies cost: You use $4 worth of supplies per office.
3. Total cost per office: The sum of equipment and supplies costs is $315 + $4 = $319.

Next, let's calculate the revenue generated per office:

You charge $25 per office.

Now, to find the number of offices you need to clean to break even, you can divide the total cost by the revenue per office:

Break-even point = Total cost / Revenue per office

Break-even point = $319 / $25 = 12.76

Since you cannot clean a fraction of an office, you would need to round up to the nearest whole number. Therefore, you would need to clean at least 13 offices to break even.
