Answer for screen readers
The best estimate of the total number of eighth-grade students who participated in the Speech Club from 1991 through 1996 is approximately 340.
Steps to Solve
-
Identify the Years in Question We need to focus on the years from 1991 to 1996. This covers the years: 1991, 1992, 1993, 1994, 1995, and 1996.
-
Extract the Number of Students for Each Year From the graph, extract the number of students who participated in the Speech Club for each of the relevant years:
- 1991: Approximately 50 students
- 1992: Approximately 40 students
- 1993: Approximately 70 students
- 1994: Approximately 80 students
- 1995: Approximately 60 students
- 1996: Approximately 90 students
-
Calculate the Total Number of Students Add the estimated number of students for each of the years: [ 50 + 40 + 70 + 80 + 60 + 90 ]
-
Perform the Addition Calculate the sum step by step:
- First, add (50 + 40 = 90)
- Next, (90 + 70 = 160)
- Then, (160 + 80 = 240)
- Now, (240 + 60 = 300)
- Finally, (300 + 90 = 390)
-
Determine the Best Estimate From the sum of approximately 390, we need to choose the closest answer option provided:
- A. 110
- B. 200
- C. 310
- D. 340
The closest estimate is 340.
The best estimate of the total number of eighth-grade students who participated in the Speech Club from 1991 through 1996 is approximately 340.
More Information
