First thoughts are probably that scheme 1 is the best because he will get an extra £20 next week (the other two schemes will only give him £18).

The real decider however is the 20% pay cut at the end of the week. 20% of £120 is £24 so he will end up earning only £96 each week!

 
Computer Teacher, do your students have access to computers?
Do you have "Laptops in Lessons"?

Whether your students each have a TabletPC or share a desktop PC, this activity lends itself to eLearning (Engaged Learning).
