Answer to Question 1

a) Combinations a and b have the same amount of hamburgers but different amounts of milk shakes.
b) Sarah most prefers combination d because it is on the highest indifference curve.
c) Sarah least prefers combination a because it is on the lowest indifference curve.
d) Sarah is indifferent between combinations b and c because they are on the same indifference curve.

Answer to Question 2

Price elasticity of demand = 10/-20 = -0.5 . Since the absolute value of the price elasticity is less than one, the demand for toilet paper is inelastic.
