Answer:

x = 15, y = 5

Step-by-step explanation:

total score of A = 6x

total score of B = 25*8 = 200

total score of C = 20y

(6x+200)/(x+25)=7.25

6x+200 = 7.25x+181.25

18.75 = 1.25x

x = 15

and

(6x+200+20y)/(x+25+20) = (6x+200+20y)/(x+45) = 6.5

plug in x

(290+20y)/60 = 6.5

290 + 20y = 390

20y = 100

y = 5
