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 16% of your total grade, each major test is worth 21%, and the final exam is worth 42%. Compute the weighted average for the following scores: 65 on the lab, 70 on the first major test, 61 on the second major test, and 76 on the final exam. (Enter your answer to one decimal place.)
