It’s a function because it passes the vertical line test
So plug in the number of passengers into each equation and see which answer matches Layton's. then from all the answers you find from plugging in the number of passengers, choose the cheapest one for B
6 4/5 as improper fraction is 34/5
5 3/4 as improper fraction is 23/4
3 1/3 by 25/4 is 8/15
14/3 by 3 1/2 is 4/3
3 1/4 by 5 1/2 is 13/22
F(x)=(x)-1 I think that’s the answer but use Desmos to figure out
I think the correct answer is B. It is the triangle case SSA that may have one, two, or zero solutions. This case can have either number of solutions but it depends on the sides of the triangle given. Having one solution can be all of the cases except SSS, having 2 solutions can only be applied to SSA.
