a) Three individuals: Dan, Sue and Benz can use their time two activities - farming and running a business. Using the following coordinates {(0,20), (10,20), (16,16), (20,10), (21,0)} use graph that will help to address the following questions.

i) What is the opportunity cost of running a business, in the first 5 counts?

ii) What is the opportunity cost of making the first two farm products? (Be accurate).

iii) If sue comes position two from least opportunity cost of producing farm produces, what is her opportunity cost of one produce when running the business?

iv) How many farm products can Sue get if all herm time is spent in the farm? (Use table to show possibilities)

b) In the island nation of Sandilands, Grazes, Benas, Collis and Dante are the only residents. Under the northerly Sea of Ferocity, there are two economics activities: small scale farming and fishing. These two activities require water. In order to produce these two goods, a special type of capital called a "water tank" is required. Water tanks are distributed differently among individuals. For each unit of food, the following table shows how many oxygen tanks each person has and how many are required to make it:

Grazes Benas Collis Dante

Water (Tanks) 6 10 8 15

Small scale farming (tanks/ seedings) 1 2 2 5

Fishing (Tanks and feeds) 3 5 2 3

i) How many units of the farm produce can be produced if everyone decides to only catch practice farming? How much fish can everyone produce if they all decide to collect only rear fish?

ii) What are the opportunity costs for each person of making produce in the farm? What are the opportunity costs associated with producing fish for each individual? (Put your answers in the table)

iii) For 1 farm produce in terms of fish, determine the acceptable trading price range. How many farm produce can one fish be traded at within an acceptable price range?
