A worker earns ₱610 per day and worked 22 days this month. What is the gross pay?
Correct answer: A. ₱13,420
₱610 × 22 = ₱610 × 20 + ₱610 × 2 = ₱12,200 + ₱1,220 = ₱13,420. The daily rate here is only an example. Splitting 22 into 20 + 2 is a quick way to multiply mentally, and gross pay is the amount before any deductions.
