5 5
t≤5
his mistake was that he used ≤ for at least instead of using ≥. so at end, when I solved, I saw that Sven should spend 5 minutes or less on each scale.
3.5, it is the coefficient and describes how many n there are

Answer: 11 because I don’t even know
So hmmm let's say, the pitcher has "x" cups when full
so, it was (3/4)x then 4 cups came out, went down to (2/3)x
now, if we subtract (2/3)x from (3/4)x, their difference will be the 4cups that were served
thus

and surely, you'd already know what "x" is
