In your biology class, your final grade is based on several things: a lab score, score 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 30% of your total grade, each major test is worth 22.5%, and the final exam is worth 25%. Compute the weighted average for the following scores: 91 on the lab, 83 on the first major test, 90 on the second major test, and 84 on the final exam. Round your answer to the nearest hundredth.
