Allan just finished a great meal at a restaurant in wisconsin. the sales tax in wisconsin is 5%, and it is customary to leave a tip of 15% for the server. the tip amount is calculated on the price of the meal before the tax is applied. (sales tax is not calculated on tips.)

Look, when you want to do something like put it like x^2. x2 could mean x² or x₂. so to clear confusion, know the notation. to find the product multiply the x's and you get -8x and the y's and you get 6y. since it's all being multiplied it is just -8x6y, or answer a. although the better answer is -48xy(combining -8 and 6) because you should multiply constants whenever you can.
