44
Step-by-step explanation:
let boys be x and girls be y
x/y=5/6
x=5y/6....(1)
if 6 boys join the club that will be x+6
Therefore:
(x+6)/y=13/12
13y=12x+72
13y-12x=72
Recall x=5y/6
Therefore:
13y-12(5y/6)=72
13y-(2*5y)=72
13y-10y=72
3y=72
y=24 people
Therefore:
x=(5*24)/6
x=20 people
Therefore people in the club before are 20+24=44

Step-by-step explanation:
If y ∝ x, then y = kx.
So, the constant of proportionality is given by 
Case 1:
$18.36 for 3 pizzas
Therefore, the constant of proportionality is 
Case 2:
$4.17 for 3 pounds of bananas.
Hence, the constant of proportionality is 
Case 3:
$16.48 for 4 pounds of potatoes.
Hence, the constant of proportionality is 
Case 4:
2 cups of flour to make 24 cookies.
Hence, the constant of proportionality is
