1.one store charge 10% sales tax for cloth and 5% sales tax for jourey, Alice各买了一样，use totally $109, the price of the bracelet including tax is $20, what is the price of the clothing including tax? (answer: $80) (trick: pay attention to "tax" and "sales tax")
==========================================
Can't find the trick! why not 109-20=89?

I agree with you. you can check my "jijing taolun 10".

I think the problem is wrong, try change "including" to "excluding", you will get $80. I don't think ets will trick you on tax and sales tax in a math problem.
