Answer:
Equation: 
Step-by-step explanation:
The equation that represents a direct variation between variable x and variable y is given as
. Where, k is the constant of proportionality.
Find the value of k given that x = ⅓ and y = 12.
Plug the values into the equation.


Multiply both sides by 3


Substitute the value of k into 

Equation: 
Answer:1/20
Step-by-step explanation:
1/2=10/20
1/5=4/20 1/4=5/20
4/20 + 5/20 = 9/20
10/20 - 9/20 = 1/20
Let x be the value of the his purchases without the discount. The $64 is the value of the 32% discount.
64 = 0.32x ; x = 200
Thus, he should have paid $200 if there was no discount. The amount he paid (p) is only 68% of this value. p = (0.68)(200) = 136. Hence, he paid only $136.
