Could someone give me a step by step on how to solve this ? At a local restaurant, a couple ordered two dinners for $12.50 each and two drinks for $1.50 each. If the couple left an 18% tip, what was the total cost of the meal?

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.
