Imagine a customer buys three items: a shirt for ₱450.00, a cap for ₱275.50, and a bag for ₱1,200.00. They give you a ₱2,000 bill and a 15% discount coupon applicable to the highest-priced item. How much change should they receive? Walk me through your calculation.

Situation

While volunteering at a school bazaar, I was assigned to man the payment booth during a peak hour. A customer approached with multiple items and a discount voucher, and a long line was forming behind them.

Task

I needed to compute the final amount quickly and accurately to keep the queue moving and avoid any short-changing.

Action

I first mentally identified the highest-priced item (₱1,200 bag) and calculated 15% off: 10% is ₱120, 5% is ₱60, so ₱180 discount, making the bag ₱1,020. Then I added the other items: ₱450 shirt + ₱275.50 cap + ₱1,020 bag = ₱1,745.50. The customer tendered ₱2,000, so I subtracted: ₱2,000 − ₱1,745.50 = ₱254.50 change. I counted it back aloud: ₱254.50 plus a receipt, and placed it in an envelope to avoid misplacement.

Result

The customer smiled and thanked me for the clear breakdown. My supervisor, who was observing, later praised my calm handling and said I prevented a potential bottleneck at the booth.
