This question is obviously set in a parallel universe where getting 7% interest is possible. Presumably a rip in the spacetime continuum makes it possible for us to observe the other universe, so time is elastic. You already have the $28,000, you always have, and always will. Were you told that cricket chirping is a linear function of temperature? Otherwise there is no way to answer. barfo
Yeah, we were told something about scientist discovering what a appears to be a linear connection between chirping and temp and to figure out the equation before solving. To tell you the truth, I didn't spend much time on the open ended questions. All 25 questions were worth 3 points apiece and if you didn't write every step down perfectly, write down the answer how they wanted it (Vertex = 4, 19.5), and boxed in you answer then you couldn't get the full 3 points but you got a point if you wrote down anything. Not the mention two of the three questions were very time consuming, time I felt I could be spending on making sure my multiple choice answers were correct.
I'm with Barfo on this one. It also reminds me of a test I had to take when applying for an engineering position coming out of the Navy. It was a complicated, potentially-trick thermodynamics question. I decided that since I had already taken the afternoon off for the interview, to be kind of a show-off and go into some depth about stuff I'd learned and studied for my DoE Nuke Exam. The proctor told me that I'd missed the question, and he'd never heard of the equations I'd tried to "make up". At that point, I withdrew from consideration for the position.
