Okay, so to make 1.95 a 2 we need to add .05. Now we can just figure out the difference between 2 and 13 and add the .05 later.
13-2=11, so we know the difference between 1.95 and 13 is 11.05.

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:
Step-by-step explanation:
(x+1)(x−3)(x−4)
=((x+1)(x−3))(x+−4)
=((x+1)(x−3))(x)+((x+1)(x−3))(−4)
=x3−2x2−3x−4x2+8x+12
=x3−6x2+5x+12
