In a barter society it has been established that: 12 bananas = 2 paw paws = 1 coconut -10 potatoes
100 potatoes = 1 shark's tooth necklace
1. How many bananas are required to buy' two coconuts?
2. How many paw paws are needed to buy 50 potatoes?
3. If you had 70 potatoes, how many bananas would you trade for them?
4. How many coconuts would you need to buy a shark's tooth necklace/
5. What would you do if the owner of the necklace said he did not want coconuts but would accept
bananas? How many bananas would you need?
6. You have one coconut and wish to get some potatoes but you only want 5 potatoes, not the 10
potatoes that one coconut would buy. Can you suggest at least one way of getting just 5 potatoes?
