The correct expression for this question would be: (50+85)+ n(11+8). That is assuming that it was 50$ transportation for everyone, not 50$ per person (and also 85$).

3/4 ÷ 7/8 =
6/7 is the answer to your question.
There is now 1/4 or half a liter left of juice still.
30 + 8 = 38 desks
38 x 4 = 152 legs
If you did not add those eight desks then you will have 120 legs.
So, the amount of legs will go up by 32 if you add 8 more desks.
First, u find conman denominator which is 15 so 2/5=6/15 & 1/3=5/15, which adds up to 11/15, so the remaining fraction that kendrs has to wash is 4/15
