also I got 9 and 5 for the last question with an amount of 505
Conflict on this one - not sure yet bro - I've got 9 and 4 so I think I've got one of the values correct at least haha

Can't remember WXYZ well bro - tell me what you got,
w = 11 because they tell you the float is 1 so 17 - w - 5 = 1 therefore w = 17-5-1 which is 11
z = 4 because that was the shortest going back when the early was 3 ..
y = 17
I can't remember x ..

I got 11 and 4 as well and i just asked one of my classmates and it's also her answer so i suppose this should be right...
