A basketball player averages 13.5 points per game. use this rate to find the value of x, the number of points scored in 7 games.

Knowing that a ratio applies to the same situation in just a larger/smaller scale; 

(13.5)(7)=x (where x is the predicted number of scores) 
94.5=x 

Therefore, the player should score 94.5 points in 7 games. 

Hope I helped :)
