You got all of the points on the assignment, that's 100% of 20 points or 20 points. You got 87% of the marks on the midterm so that's 87% of 40 or 0.87 × 40 = 34.8 points. Thus, so far you have 20 + 34.8 = 54.8 points. You need 80  54.8 = 25.2 more points to pass the course, so you need 25.2 of the 40 points on the final exam. What percentage of 40 is 25.2? Penny
