Exercise 2

Mr. Vold is a sadistic teacher who likes writing lots of exam questions. He usually starts out the semester with only 10 questions on the first exam, but for each subsequent exam he writes one and a half as many questions as were on the previous exam! Since there's no such thing as half a question and Mr. Vold likes writing questions, round your answers up to the next integer.

(a) How many questions are on the second exam of the semester?

(b) How many questions are on the third exam of the semester?

(c) How many questions are on the fifth exam of the semester?

(d) If Mr. Vold wrote 20 exams in a semester, how many total exam questions would they have all together?
