Aplumber 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 $
