8. Our first step in solving this problem is subtracting the cost of renting the studio from her total budget. This is:
318-109.50 = 208.5
Now, we divide 208.5 by 15 to see how many people can attend.
208.5/15 = 13.9
Because we are looking for the amount of people that can attend the class, we round 13.9 down. This means that 13 people can attend the class, so A. Is the right answer.
