The railroad companies of Pacific Union and Central Pacific were both built with
massive government subsidies often on a per-mile basic in the late 19th century, which

subsidies. It turned out to be much more successful than either Pacific Union or Central
Pacific. What could account for this apparent disparity?

Scenario 1
Let's say that you only have enough time to take two college courses in a semester. You
also only have 15 hours per week to devote to both courses " French and Economics.
Assume that you could earn a "70" in both courses even if you didn't study at all for
either course. If you study for either course your productivity is such that each hour
spent studying for a course earns you 2 points for your grade in that course.
Using Scenario 1 what is the maximum grade you could earn in any one course? If you
wanted to earn a grade of 90 in French but no better than a 70 in economics are you
operating on your budget constraint? Why or why not?
