  • "To make this a "real" problem, the time frame needs including because any company would have to supply this. The option 1 calcs are good, but 9 days @£2 is too simple. So, good idea that could have improved options."

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!
