3 for $100.50 or
5 for $150.50
Part A: Does the information on the sign represent a proportional relationship?

yes or no question

No it does not represent a proportional relationship. 100.50/3 is 33.5 vs 150.50/5 is 30.1 :)

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.
