An investor tracked the closing price of a stock for five consecutive days.

Table (Closing Price) Columns: Day; Closing price (USD) Rows:

  • 1: 48
  • 2: 51
  • 3: 50
  • 4: 54
  • 5: 57

Which of the following is closest to the percent increase in closing price from Day 1 to Day 5?

  1. 12.5%12.5\%
  2. 15.0%15.0\%
  3. 18.8%18.8\% (correct answer)
  4. 9.0%9.0\%
  5. 2.0%2.0\%

Explanation: This question tests data interpretation skills using a table of stock closing prices over five days. The table lists days 1 to 5 with USD prices. To find the percent increase from Day 1 to Day 5, calculate (57 - 48)/48 × 100% = 9/48 ≈ 18.75%. The closest is 18.8%, justifying choice C. A common misread is using Day 2 or another as the base, like from 51 to 57 = about 11.8%, not matching options directly. Another error could involve absolute increase divided by average, approximating 15% as in B.
