91. You are organizing a Pub Night at your school. You are going to sell beer for $2 and pop and chips for $1 each. Four people will be working behind the bar, and they have all assured you that because the prices are easy to remember and easy to add they will be able to handle collecting the cash and serving of the drinks and chips. They suggested that you give them each a $20 float of loonies and toonies to have in their pockets for change.


Required:


Critique the proposed system and suggest improvements in the way the Pub Night could operate.

92. Which of the following investments would you prefer? Support your answer.


A) A $10,000 savings bond that grows at the rate of 6% per year compounded semi-annually, for 5 years.
B) One lump sum payment of $5,000 now plus another $5,000 after 2 years. You estimate you could invest the first payment at 5% and the second one at 6%.
C) A single payment of $13,500 in 5 years.
