Pocket Money

Sally and David have agreed to work for their Mum over

the holidays. The pay they get will vary though. Sally will

get $10 for the first day she works and two more dollars

for every day she works after that.

David, on the other hand, will get $1

for the first day he works but for each

day he works from then on his pay will

be doubled. Who would you rather be

and why?
