a physicians office provides three types of service: brief, intermediate, and extended. Total annual costs for the office are 400,000. Hourly labor rates for the physician, nursing staff, and administrative staff are 100, 25, and 15, respectively. Additional data is as follows.

Average supply cost physician. nursing admin. patient visits per year

Brief: $1 12 15 30 3600

Intermediate $2 24 15 30 1800

Extended $5 42 15 30 600

Assuming that indirect/overhead costs are allocated to each type of service equally, what is the total cost of providing each service?

Brief - 47.79 / Intermediate - 75.97 / Extended 108.97 these are the anwsers I am just unsure how to solve it
