20% off $200 is $160.00

How to work out 20% off $200

20% of $200.00 is $40.00 (0.2 x 200). Take that from $200.00 and the sale price is $160.00.

Add sales tax

Sales tax is normally charged on the discounted price. At 8% tax, $160.00 becomes $172.80 at the till, against $216.00 without the discount, so the sale puts $43.20 back in your pocket.

Stack a second discount

If a coupon takes another 10% off the sale price of $160.00, you pay $144.00. That is $56.00 off the original $200.00, an overall discount of 28%, which is less than 30% because the second cut applies to a smaller number.
