In your biology class, your final grade is based on several things: a lab score, scores on two major tests, and your score on the final exam. There are 100 points available for each score. However, the lab score is worth 23% of your total grade, each major test is worth 24%, and the final exam is worth 29%. Compute the weighted average for the following scores: 95 on the lab, 64 on the first major test, 65 on the second major test, and 100 on the final exam.
