Option C
Lets say you get 10$ for 1 hour for doing a job
And it took you , say, 5 hours to complete a job.
So you will earn 50$ , and is evaluated using multiplication, as 10$* 5 hours = 50$
Now in this question:
They charge you 15$ for 1 hour
And if you did ice skating for “h” hours then you will give them 15$*h = 15h
Now for skates , you will be charged 5$ for once
So that amount will be added to our initial charge
So the expression will look like : 15h + 5
Which is option C
