Hint:

For line graph averages, sum all data points and divide by the number of points, ensuring accurate addition.

Answer 1

The Correct Option is B

- Step 1: Sum the sales. January: 200, February: 250, March: 300, April: 280, May: 320. Total = $200 + 250 + 300 + 280 + 320 = 1350$.
- Step 2: Calculate average. Number of months = 5. Average = $1350 \div 5 = 270$.
- Step 3: Verify with options. Average of 270 matches option (2).
- Step 4: Cross-check. Recalculate: $1350 \div 5 = 270$. No errors.
- Step 5: Final conclusion. Option (2) 270 is the correct answer.
