An Island Economy Produces Only Two Goods, Coconuts and Pineapples

An island economy produces only two goods, coconuts and pineapples. There are five people (A,B, C, D, and
E) living on the island with these preferences:
A has a strong preference for pineapples.
B has a strong preference for coconuts.
C doesn't care for pineapples (assigns no value to them).
D doesn't care for coconuts (assigns no value to them)
E will only consume pineapples and coconuts in the fixed
proportion of one pineapple to one coconut.
For each of these five individuals, construct a representative indifference curve with pineapples on the vertical axis and coconuts on the horizontal axis. Discuss the shape of the indifference curves and relate them to the MRS.
