7.  In order to solve this problem, we subtract 70 from Hal's amount of money and multiply the result.  This written out is:

(170-70)*5

This is equal to 500, so Bob has $500.  D. is the correct answer.

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.

The last one hope it works
