Answer:
Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
Step-by-step explanation:
Let 
denote the number of rafts seating 3 people and 
the number of rafts seating 5 people. The total number of rafts is 13, so 
. We can also assume that every raft is filled to the brim (it isn't stated explicitly though, but it's probably the intention of the question maker), so 
.
It's always a good idea to put these equations under each other:
We can subtract the first equation three times from the second one to obtain 
Now, substitute this found value for into 
and we see that 
. We are now done: Peter rents 6 of the rafts seating 3 people, and 7 of the rafts seating 5 people.
75,88,90,96,98,100
minimum = 75
Q1 = 88.....this is where the box begins
Q2 (the median) = (90 + 96) / 2 = 186/2 = 93....this is the line in the box
Q3 = 98....this is where the box ends
maximum = 100
88_93______98
