The answer is: $200.  If 4  members and 8 guests wanted to use the club, it would cost $200 an hour.

m = members, and g = guests

m costs $10/hr

g costs $20/hr

You must multiply the cost/hour by the quanity of the variable.

So, you could set up and solve the equation as:

10(m) + 20(g) = r

10(4) + 20(8) = r

40 + 160 = r

200 = r

Therefore, the answer is $200.
