See the attachment please.
Step-by-step explanation:
Statistics!! All work is on the picture, plus the boxed answers.
I'm not completely sure about this answer but here is what I got: 100•15=1500 for one day of the food booth. 50•22=1100 one day for the game booth. 1500+(x9) and 1100+(x8). (1500+x)+(1100+x)=x
21.50 x 25 = 537.50
10.75 x 5 = 53.75
537.50 + 53.75 = 591.25
That means they have a common denominator. Hope this helps!
