A shirt costs 200. It is discounted 20%, then the new price is discounted another 10%. What is the final price?

What is the answer to the 20% then 10% off riddle?
The final price is 144. A 200 shirt at 20% off becomes 160, then 10% off 160 gives 144 — that's only 28% off, so paying as if it were 30% off means you overpay.
Is 20% off then 10% off the same as 30% off?
No. Two successive discounts of 20% and 10% equal a total of 28% off, not 30%, because the second discount applies to the already-reduced price.
How do you calculate two discounts in a row?
Multiply step by step: 200 x 0.8 = 160, then 160 x 0.9 = 144. You can't just add the percentages together.
