c.

d.
$72

b.   $146

The number of hours of parking =72 hours

The number of half hours in 1 hour =2

The number of half hours in 72 =

okay wait before i answer, is this for your points on a graph?

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
