Step-by-step explanation:
A real number MUST be able to be represented on a number line. 
All numbers can be placed on a number line including irrational numbers.
Numbers like π can be placed between 3.13 and 3.15. It is a number.
Numbers like x or ∑ isn't a "REAL" number because it has no value. 
 
        
             
        
        
        
Since it varies directly, divide the number of shots by the number of goals:
48 shots / 4 goals = 12 
This tells you they score a goal every 12 shots.
Multiply shots needed by number of goals:
12 x 3 = 36
They need 36 more shots to score 3 more goals.
