Janie spends 10 hours per week making flower arrangements. Yesterday she was offered an after-school job by the pet store in the mall, which she often visits to look at the animals. If she took this job working ten hours a week, she could make $2,500 per year. She has $600 invested in her flowers, and she could have that money earning interest at one percent per year in a savings account. What is Janie's total opportunity cost of staying in business for herself this year?

In a speech before the american society of newspaper editors (april 16, 1953), president eisenhower stated: "every gun that is made, every warship launched, every rocket fired signifies, in the final sense, a theft from those who hunger and are not fed, those who are cold and not clothed. this world in arms is not spending money alone. it is spending the sweat of its laborers, the genius of its scientists, the hopes of its children. this is not a way of life at all in any true sense. under the cloud of threatening war, it is humanity hanging from a cross of iron." do you agree or disagree?
