Answer 9

About which part, setting up the equation, reducing the equation, or dividing 315 by .7?

Answer 10

pretty much all of it

Answer 11

Ok we can go through it slowly.
First, we now that the product x was reduced by 30%. This means that originally we had some x and muliplied it by .3 to get the discount. Instead of doing this separately, we take 70% of the original x to find the discounted price. So that is .7x, which we know to be equal to 315. Then just divide .7 on each side (remember % is just a fancy way of saying that number per (divided by) cent (100).
