A student's course grade is based on one midterm that counts as 10% of his final grade, one class project that counts as 10% of his final grade, a set of homework assignments that counts as 35% of his final grade, and a final exam that counts as 45% of his final grade. His midterm score is 62, his project score is 97, his homework score is 75, and his final exam score is 70. What is his overall final score? What letter grade did he earn (A, B, C, D, or F)?

For a Saturday service, if the weather is sunny, you will take in $9,000; if the weather is cloudy, you will take in $2,000; if it is rainy, you will only take in $1,200.

A math course has two midterms and a final exam. Midterm 1 is worth 18% of the final grade, midterm 2 is worth 36% of the final grade, and the final exam is worth 46%. The teacher assigns grades as marks on 100. If a student recieved a mark of 78.1 on the first midterm and 72.6 on the second midterm, what mark does he need on the final exam to get a final grade of 80 in the course. Please use excel for all calculations. Give the answer to 5 decimal places.
