You build and sell toy boxes. so far, you have built 15 toy boxes that you will sell for $60 each. how much money will you have if you build 20 more toy boxes and sell all of them?

15 plus 20 equals 35
35 times 60 equals 2100
they will make you $2100

Since you already have 15 boxes, and you want to build 20 more, you add the two numbers. 15+20=35.  Then, you multiply 35 by 60 since you are selling each for $60. 35x60=2100. So you will have $2100 dollars if you sell 35 boxes.

Is it multiple choice

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.
