Suppose you were starting in the office cleaning service. we have spent $315 on equipment. to clean an office, you use four dollars worth of supplies. you charge $25 per office. how many officers must clean to break even?

Number of offices to be cleaned to cover the cost of equipment =15

Cost of equipment =$.315 Cost of supplies =$.4 Charge per office =$.25

Number of offices to be cleaned to cover the cost of equipment =x

Then -25x − 4x =315

21x =315

x=315

21=15

Number of offices to be cleaned to cover the cost of equipment =15
