a parking garage charges $0.75 for each half hour (or part thereof) for the first hour,$1.00 for each additional hour (or part thereof), and $16.00 daily maximum. If the cost C(t) is a funtion of the time parked, graph C(t) any help with what equations i need to use would be great. Thanks! 2.

any help with what equations i need to use would be great. Thanks!
this will be a step function ...

$C = .75$ , $0 < t \le 0.5$

$C = 1.50$ , $0.5 < t \le 1$

$C = 2.50$ , $1 < t \le 2$

$C = 3.50$ , $2 < t \le 3$

$C = 4.50$ , $3 < t \le 4$

and so on until $C = 16$
