Which category of unemployed individuals makes up the greatest share of those who are unemployed?

Kevin has a lot of free time and he decides to pick up a new hobby. He has two options—he can take art classes or can sign up for French cooking classes

He estimates that the art classes would cost him $70, and would provide him with a benefit of $100. On the other hand, the cooking classes would cost him $120, but provide him benefits worth $160. Use cost-benefit analysis to arrive at the optimum choice for Kevin.

Suppose a medical study reveals new benefits to consuming beef and at the same time a bumper corn crop reduces the cost of feeding steers. The equilibrium price of beef will

A) fall. B) perhaps rise, fall, or stay the same, but more information is needed to determine which it does. C) stay the same. D) rise.
