Let http://webwork.daltonstate.edu/webwo...9e766d31c1.png represent the expected score for a student who studies http://webwork.daltonstate.edu/webwo...5b59f2bc11.png hours for a test. Suppose http://webwork.daltonstate.edu/webwo...2415dd5411.png and test scores must be integers.

What is the highest score the student can expect?

If the student does not study, what score can he expect?

If the student needs a grade of 80 to pass the class, how many hours of studying are necessary?

I dont know how to go about doing this problem. Someone mind not doing the problem for me but guiding me along the way of how to do it?
