Mr and mrs waugh want to use a caterer for a birthday party for their twin sons. the manager says the cost for a family of four would be $160. however, the sons want to invite 8 friends, making 12 people in total. the cost for this would be $360. if the total cost in each case is made up of the same cost per person and the same fixed cost, find the cost per person and the fixed cost.

$60 fixed price        $25 per person

Step-by-step explanation:

x=price per person

c= fixed cost

4x+c =160

12x+c=360

I will multiply the first by -1:

-4x -c=-160

12x+c=360

ADD BOTH:

8x     = 200

x=25  ($25 per person)

25*4=100

160-100 = 60 (fixed cost =60)

25*12=300

300 + 60(fixed cost) = 360
