I attached the picture of the question since it is too much to type.

3. Assume you have interest in only two goods: food and environmental quality. That is, these goods are the only ones that provide utility to you. Consider the following graph: Let point A correspond to 90 units of food and 10 units of environmental quality. Let point B correspond to 50 units of food and 60 units of environmental quality. a. Label the axes. What is the technical name of the curve mentioned earlier? b. Calculate how many units of food you are willing to give up in order to obtain one more unit of environmental quality so as to maintain the same level of satisfaction
