I don't know if the word step function applies to this question.
Let x = hours
Let C(x) = total cost
Then C(x) = 25x
This is a linear function.

This is the least integer function (LIF) returning the least integer greater than or equal to any real number x argument, denoted [x).

R(x) = 25( [x) )

So, if he works for less than one hour, the LIF returns 1 and he gets $25. If he works for 4 hours and 2 minutes, the LIF returns 5 and he gets $125.
