A plumber charges a fee of $25 plus $30 per hour on the job. Make a table of values for the total charge depending on the number of hours the plumber works. Determine if this can be defined by a linear or an exponential function. What is the function?

linear, $T = 25 + 30h $
exponential, $T = 25(30)^h $
exponential, $T = 30(25)^h $
linear, $T = 30 + 25h $
