Paige: Peter, you had Miss Flood for geometry, right? Peter: Yeah, why? Paige: She gave us this handout to help us prep for tomorrow's test. The first thing that's strange is there's only one problem on it. Peter: "Petey the procrastinator puts off studying and gets a zero on the first test of the spring semester." "If the test is worth 10 percent of Petey's semester grade, what must Petey's average grade for everything else be if he wants to eke out a 'B' in the class (83 percent)?" Paige: The second thing is what does this have to do with geometry? It's algebra! I think she's losing her mind! Did she do things like this when you had her? Peter: Actually, this DOES seem oddly familiar somehow...
Assuming that there are a total of 10 tests in the semester and each test would is worth 10 percent each.
Petey would need at least to score 9.22 or 9.3 for each test to get 83 percent.
In physics term, he were attached to another object by an inclined plane, wrapped helically around an axis.
