Trent earns scores of 66, 84, and 72 on three chapter tests for a certain class. His homework grade is 60 and his grade for a class project is 85. The overall average for the course is computed as follows: the average of the three chapter tests makes up 50 % of the course grade; homework accounts for 20 % of the grade; the project accounts for 10 % and the final exam accounts for 20 % . What scores can Trent earn on the final exam to pass the course if he needs a “C� or better? A “C� or better requires an overall score of 70 or better, and 100 is the highest score that can be earned on the final exam. Assume that only whole-number scores are given.

In a study of over 15,000 teens, 62% of boys
and 55% of girls consumed sugar-sweetened
soda on the previous day. When asked to
compute the boys' percentage with the girls'
percentage, two students gave the answers
below.
Alma: The boys' percentage is 7% bigger than the girls'.
Bill:
The boys' percentage is about 113% of the girls'.
Show how each student computed the
percentage.
Alma: 62% - 55% = 7%

Suppose a student got an 82 on an exam that was worth 25% of the final grade, a 75 on another exam worth 25% of the final grade, and 93 for a homework score worth 10% of the final grade. They only have the final exam left, which is worth 40% of the final grade. What score is needed on the final exam to get a 90 for a final grade?
