If X is 75% of y, then what percentage y would x*10 be?

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.

Ifigured it out from watching a khan academy video , i am so sorry about the first answer. but i agree that x= 72. and now you can give the other person brainliest if you want.
