Question

You are not doing as well as you had hoped in one of your classes. So, you want to

figure out the minimum grade you need on the final exam to receive the semester grade
that you want. Is it still possible to get an A? How would you explain your calculations
to a classmate?
1. The grading scale states that you must have a 90% to earn an A for the semester.
There are five tests cach semester (four exams and one final). Given the percentage
scores on the first four exams, determine if it is possible for you to get an A with
your score on the final. Remember, the maximum possible score is 100%.
a. Exam 1 = 85, Exam 2 = 80, Exam 3 = 94, and Exam 4 = 93
Can you cam an A? If so, what score would you need on the final exam? If
not, what is the highest percent you can get for your semester grade? Explain.
b. Exam I = 82, Exam 2 = 84, Exam 3 = 83, and Exam 4 = 96
Can you cam an A? If so, what score would you need on the final exam? If
not, what is the highest percent you can get for your semester grade? Explain.
2. What is the lowest single score (percent) you could get on one of the five exams
and still receive an A? How did you calculate your score? Explain it to your friend
who believes the only way to receive an A is by carning an A on every exam. Is
she right? Why or why not?

Answer 1

1. Yes. 98 2. 50. Friend is wrong

Explanation:

1. 4 grades for a total of 352 points

For 5 grades to have an A NEED 450 POINTS

450-352=98

2. Need 450 points to make an A

100 on 4 tests= 400 points

450-400= 50
