10. Deriving demand from an Indifference mapBeth recently moved to San Dlego, where they developed a taste for drinking Americanos and eating danishes. Assume throughout this problem thatthe price of an Americano is held constant at $4.On the following graph, the purple curves (I, and /a) describe two of Beth's Indifference curves.

Given the preceding graph and knowing the price of an Americano is $4, Beth's available income for Americanos and danishes is $
