- Step 1: Sum the customers. Monday: 150, Tuesday: 200, Wednesday: 180, Thursday: 220, Friday: 250. Total = $150 + 200 + 180 + 220 + 250 = 1000$.
- Step 2: Calculate average. Number of days = 5. Average = $1000 \div 5 = 200$.
- Step 3: Verify with options. 200 matches option (2).
- Step 4: Cross-check. Recalculate: $1000 \div 5 = 200$.
- Step 5: Final conclusion. Option (2) 200 is the correct answer.
