Let the total number of cans be x and the total number of tennis balls be y,
Since increasing the total number of cans causes the total number of tennis balls to increase too, x and y is direct in proportion.
Let the constant be k,
y = kx
45 = k9
k = 45/9
= 5
The constant of the proportionality for this situation is 5.
        
             
        
        
        
Formula 
3p < 14
step 1 : 3p / 3 < 14 / 3  
; divide 3p, by 3, and 14 by 3
p is about 4.67 ( rounded, original is 4.66666666666666.... etc)
