To make extra money at school, Sofia starts a house painting
business. Sofia's start-up costs are $480 (including permits
and license fee). Additionally, Sofia must purchase painting
supplies for each house at a cost of $520 per house. Sofia
charges her customers $2,400 per house.
It takes 48 hours of working time to paint a house. Sofia has
24 hours a week to dedicate to her painting business. She
works every week for one year (52 weeks). Sofia can hire a
maximum of 2 other painters to join her team. Each painter
works 24 hours per week and she pays each painter $18 per
hour. Assume there is only one team of workers (that always
includes Sofia), and that her work is so good, she keeps
getting offers for jobs.
Assume Sofia does not pay herself a salary, but instead earns
all profits of the business.
