Q1 · In the diagram, an individual initially chooses combination N on budget line LM 9708/31 Oct/Nov 2009

3 In the diagram, an individual initially chooses combination N on budget line LM. An increase in his money income accompanied by an increase in the price of good Y causes his budget line to shift to RS, and he now chooses combination T.
