Mr. Blake’s biology class is divided into three sections. The same test was given to each section. The table above shows both the lowest score and the range of scores on this test for each section. What is the overall range of all scores in all three sections?
- A25
- B27
- C28
- D31
Show the answer
Correct answer: D
First, calculate the highest score for each section by adding the lowest score to the range:
Section I: 65 + 28 = 93
Section II: 62 + 25 = 87
Section III: 67 + 22 = 89
The overall highest score is 93, and the overall lowest score is 62. Thus the overall range is 93 − 62 = 31.
