Determine the condition under which job Shane should collect and explain

By the 4th hour of working, both jobs pay 80, but Job B will pay less by the 5th hour, and continues to pay less as time progresses after that.

Draw the graph of Job b on the same graph as A and you'll see exactly when A passes B.

He'll make more at job A if he works more than 4-5 hours, but more at job B if he works less than 4-5 hours (again, don't know at exactly what time A passes B, wouldn't recommend putting "4-5" on a paper)

Step-by-step explanation:

hour          job A pay           job B pay

 0                    $0                    $30

 1                   $ 20                $42.50

 2                   $40                   $55

 3                   $60                $67.50

 4                   $ 80                  $80

 5                   $100               $ 92.50

Hope this helps!
