Suppose you plan to take summer courses. The cost of tuition and textbooks is $1,200, housing will cost you $400, and you'll spend
$300 on food. If you decide not to take courses in the summer,
you'll live in your parents' house for free and spend only $100 on
food. Also, if you don't take courses in the summer, you'll work full
time and could earn $5,000. You can still work part time while
taking courses, but you will only earn $1,000. What is your
opportunity cost of taking courses in the summer?
