Someone came into my shop and stole $100 out of the register. the same person came back 5 min later with the same $100 and purchased $70 dollars worth of items and i gave them back $30 dollars in change. how much money did i lose?

Val and tony get paid per project. val is paid a project fee of $44 plus $12 per hour. tony is paid a project fee of $35 plus $15 per hour. write an expression to represent how much a company will pay to hire both to work the same number of hours on a project.
