Answer:
Infinity
Step-by-step explanation:
In the case when the tea and scones are considered to be the perfect complements also you give preference one cup of tea over the one scone
Plus the indifferent curve with tea should be plotted on the vertical axis
So in the case when there is 2 cups of tea with one scone so at this point, the MRS should be at infinity as the indifference curve should be in downward sloping because we presume that there is preferences done at monotonicity
