 P: 349 Agreed on all questions now. Questions 8 and 9 are very poor. Because 8 doesn't specify any units, any number will do. For example, the correct answer is $11bn/yr. But this can also be written as$22bn/two years, or $5.5bn/six months. Any number will do because you can hide the matching fiddle factor in the units. The kicker is that for question 9, E is correct if you use$11bn/yr, but D is correct if you express the same value in other units. This is why units are important, kids. Rant over.
