I'm pretty sure that the answer to number 10 is 375, not 75 because it was a decrease from something to 120, and 75 to 120 is not a decrease.
ReplyDeleteyeah, I got the same as Cleo... I also got -56.25% on 8... can you at least explain how to do it?
ReplyDeleteNumber 10 is supposed to be 375. I blame my keyboard for not typing correctly, because clearly nothing could be MY fault.
ReplyDeleteFor number 8, you have to remember to divide by the original value of 125, which should give you the correct answer of -36%. If you divide by 80, then you end up with the answer of -56.25% (I think).
Yeah, that's exactly what I did accidentally (n-o/n instead of n-o/o). Thanks!!!
