The original price of a jacket for sale at a department store is $80. The store is having a 20%-off sale, and you have a coupon that gives you an additional discount of 10% off the lowest sale price. How would you calculate the final selling price of the jacket?

A. Multiply the $80 original price by 0.2 and subtract the result from $80. Then multiply the new price by 0.1 and subtract the result from the discounted price.

Start with the original price, $80.

If you take 20% off, then you will be paying 80% of the original price. Calculate 80% of $80.

80% of $80 = 80% * $80 = 0.8 * $80 = $64

After applying the 20% discount, the new price is $64.

Now you apply the 10% coupon.

Since you are taking 10% off the discounted price, you will be paying 90% of the discounted price.

90% of $64 = 0.9 * $64 = $57.6

The final discounted price is $57.60
