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.

Answer:
200 ft²
Step-by-step explanation:
L = 2W
2L + 2W = 60
2(2W) + 2W = 60
6W = 60
W = 10, L = 20
A = 10 x 20 = 200 ft²
Step-by-step explanation:
100% = 4.25
1% = 100%/100 = 4.25/100 = 0.0425
how many % are 3.4 ?
we find this by calculating how often 1% (0.0425) fits into 3.4.
3.4 / 0.0425 = 80 %
