Suppose 3 out of 7 people are parents and 7 out of every 12 parents have more than one child. At the same rates, in a group of 1344 people, predict how many you would expect to have more than one child.

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.
