Todd is a plumber, and his coworker Bill is an electrician. Todd charges customers a fee of $60 just to come to their houses and then $2 per minute that he is there. Bill also charges a fee of $80 for a home visit, plus an additional $1 per minute. Last week the coworkers went to a job site together, spent the same amount of time working, and earned the same amount.
Let y represent the amount of money each person earns at the job site. Let x represent the number of minutes spent working.
Graph each function to determine the number of hours they spent working.
Hint: You will need to convert the slope into a fraction that can be plotted on this scale
Use your graph to answer the following questions:
Part 1. How much time did each person spend working?
Part 2. How much did they earn for this job?
Part 3. Explain your reasoning
