We know Mary would be indifferent between a bundle with 24 avocados and 30 grapefruits and another bundle with 30 avocados. This means that the two bundles have the same utility level for Mary. If we add more grapefruits to the second bundle, the slope of the indifference curve would have to be less than -2, which is not the case. Therefore, the second bundle must have 24 grapefruits, as this is the only option that would give the same utility level as the first bundle.
