Explanation:
direct variation would be
y = kx
inverse variation means
y = k/x
now, in our case and given example
25 = k/72
k = 25×72 = 1800
we need to use the same k for the other situation, as they are both Reisterstown the same relationship between x and y :
y = 1800/34 = $52.94117647... ≈ $52.94
it will cost about $52.94 per person, if only 34 people are going.
the meaning of all this is that the trip for the bus costs $1800. the more people ride on the bus, then the more the total of $1800 can be split as equal share per person.
if only 1 person is on the bus, he/she would have to pay the full $1800 all by him-/herself.
if there could be 1800 people on the bus, then each one would pay only $1.
