Answer:

Part 2)  5 hr

Part 3)   $80 and $160

Step-by-step explanation:

Part 2)  Equate the two pay equations:  20H = 10H + 50

             Subtract 10H from both sides:  10H = 50

              Then H = 5.  

               After 5 hours, each would have earned the same    amount.

Part 3)  In an 8-hour day, one guy would earn ($20/hr)(8 hr) = $160, and the other guy would earn ($10/hr)(8 hr) = $80.

Answer:

2. 5 hours

3. $80 and $160
