Question

Question 1: Suppose your math grade is based on the results of two tests and one final exam. Each test is worth 30% of your grade and the final exam is worth 40%. If you scored 60% and 50% on your two tests, what mark must you score on the final exam to achieve a grade of 70%

Explanation:

.3 (60) + .3 (50) + .4(x) = 70

18 + 15 + .4x = 70

.4x = 37

x = 92.5 % Good Luck .......
