Accounting break even point help please?

i need this explained to me on how to get the answer i am so confused

The price of the service will be set at $65 per visit.

One full-time nurse position can provide a maximum of 120 one-hour visits per month.If the service is contracted, the agency plans to pay the contract nurses at the rate of $45 per visit including the cost of supplies. If the agency hires the nurses, the monthly salary will be $4,000 and the agency plans on spending an average of $10 per client per visit for supplies.
Regardless of the method of service delivery (direct or contract) and regardless of the number of nurses hired, the agency plans to charge (allocate) $4,000 per month in indirect costs to the visiting nurse program. Compute four annualized BEPs assuming the following: (1) the service is contracted, (2) one full-time nurse is hired, (3) two full-time nurses are hired, and (4) three full-time nurses are hired. What are the four BEPs?

I won't give you the answers, but here's how to solve the problems:

First, identify the costs that are variable and the costs that are fixed. In all cases, the $4,000 indirect costs are fixed costs.

If contracted, the only variable cost is the $45, so each visit generates $20. That needs to cover the $4,000 indirect.

If hired, look at it in terms of a net of $55 ($65 per visit less $10 in supplies) that need to cover both the indirect costs and the nurses' salaries.
