Jesse shovels snow in the winter and tells his customers that there is a one-time supply fee of $12 and an hourly rate of $7 per hour. John also shovels snow in the
winter. John tells his customers that there is an hourly fee of $9 per hour and a
one-time supply fee of $4. When will the two workers make the same amount of
money? How much money will that be? Write both equations in slope-intercept
form (y=mx+b).
