A jackets original price is $65.00 .It is on sale for 40% off. you have to pay 5% sales tax What is the final price fir the jack

lesya [120]

Hello!

There is a discount of 40%, which means that we will be subtracting 40% of the price, and then sales tax is basically additional money added to the price, so we will be adding that.

65.00 * 40% = 26

65.00 - 26 = 39

So, the discounted price is $39. Now we must add tax on that.

39 * 5% = 1.95

39 + 1.95 = 40.95

The final price of the jacket is $40.95.
