Well I would do 7) with x and y equations again. x being good and y being outstanding. But like, you don't get really nice numbers when you solve it, though I'm unsure if that's even possible with those numbers.xD
1) x + y = 10 2) 3.33x + 6.66y = 42.30
Then it just goes the same way as always. But like, the numbers that you get aren't so nice, so if anybody has a better idea with nicer numbers where you don't have to round because she can't work 2.4 days or something, I'd love to hear it.

MATH NICE I LOVE MATH
Alright what I'm doing right now for question 7 is what you and Water wanted: a version with full numbers instead of decimals. I wrote out a list of possible values for each day if only that person did outstanding or good work. I crossed out some of the numbers in the "outstanding" list that exceeded 42.3 and the ones that added up to 10 with it in the "good" list, and then I tried to pair up the remaining numbers......
However this method would only work in theory as the closest I got to 42.30 was 43.19, which was 7 good days and 3 outstanding days. Unless I messed up somewhere along the line. OR if it's a trick question and she did work that was in-between good and outstanding, which is odd.
I also know a different way to do this that's much faster but I don't remember it right now.
EDIT: So it would look like 7(3.33) + 3(6.66)
There's really no way that she would have regular days, she would have to have a weird day in there somewhere because I wrote out a list. Unless I messed up the list, which I doubt I am
EDIT II: The method I was thinking of was Water's method now that I've looked at some of the posts on the thread. But you still don't get nice numbers with it. There has to be an odd day or two in there.

..Hm. I'll just put 3 days for outstanding I guess.. cx

I've always solved those equations with elimination, if you know what I mean.

Yeh, I know what you mean cx
Also, I have another problem my dad wants me to do. I'll write it down tomorrow.

Is it a problem like these?

I actually just had to look up what you meant with elimination, Spotted, aha. xD If what I found is right I actually was shown that at school before, but our teachers advised us against using it because often it is harder than the thing I did. We can use whatever we want to solve it, though, as long as it isn't just numbers guessing.

Well, it's a word problem so x3 ok here:
John and Rose are getting ready for school. John leaves to walk to school. It will take him 10 minutes to walk there. Five minutes after he leaves, Rose realizes that he forgot his lunch. She knows that she can run twice as fast as h walks, or-if she takes her bike-she can ride her bike three times as fast as he walks. However, her bike is locked in the garage and it will take her two minutes to unlock the bike.
Will she catch up to him faster by running (leaving immediately) or biking (after she unlocks the bike)?
Bonus question: How long will it take John to get to school after he eats his lunch?

Wait, can you clarify something? Would Rose catch up to John at school or before John got there?

I would imagine it to be at the school, however I'm not certain..

She would catch up faster by running.
10 / 2 = 5. 10 / 3 = 3.3 3.3 + 2 = 5.3
But I’m not sure about the bonus question. If she runs, then he would already be at school. If she rides her bike, he would have been at school for 18 seconds.

Nope! Not at the moment, anyway.
