Answer:
27850
Step-by-step explanation:
9/100 = x/30.95
9 x 30.95 = 278.5
278.5 x 100
100% - 40% = 60%, meaning the discounted price is really just 60% of the original 100% price, let's say the 100% price is hmmmm "x".
if 60% of the original price is $471, what is the 100% or namely "x"?

It usually helps a person to get a better idea of how much or how big something is. I'm actually not sure why, but let's use an example. You got 38 out of 43 questions on a test. when you see 38/43 you don't really know how good that score is, but if you make it a percentage (Dividing the first number by the second to get the percentage) it's 88%. You know you did well on that test.
Hello, I'll try to make this as easy to understand as possible, anyways, let's begin:
First, we know that 3 is a bigger number than 2 1/2, and since it's negative, it means they lost weight, therefore...
Jenna lost more weight than Sarah.
Hope this helped! c:
