  Solution
From the question I understand that all ice cream costs him $10, no matter however much he eats.
In this economy, equilibrium is attacined at a point where MB=MC. However, since in the given question MB is not equal to MC at any output level, thus he will consume at a point where TB=TC.
Thus, he will eat 2 units of ice cream.
