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 19% of your total grade, each major test is worth 24%, and the final exam is worth 33%. Compute the weighted average for the following scores: 70 on the lab, 60 on the first major test, 89 on the second major test, and 96 on the final exam.
