Cumulative Number of Persons Vaccinated

Study the area graph below. It shows the CUMULATIVE (running total) number of persons vaccinated in a municipality, in thousands, at the end of each week of a vaccination drive. Use it to answer the questions that follow.

What was the average number of persons vaccinated per week over the six weeks (to the nearest whole number)?

  1. 23,000
  2. 8,000
  3. 6,667
  4. 6,000

Answer

C. 6,667

Solution

Total = 40,000 over 6 weeks. 40,000 ÷ 6 ≈ 6,667 per week. (Averaging the running totals gives 23,000, which is wrong.)
