Maggie Reeves · Answer 1

The answer is 30 hours. You can solve this by a system of equations. 15 + 2h=X with h being the number of hours she worked and X being the total number of hours she worked last week. The second equation would be 3h-15=X since she worked the same amount of hours this week and last week, you can set the equations equal to each other and solve for H which gives you 30 hours.
