Answer:
y = x
Step-by-step explanation:
Given y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the given condition that y = 7 when x = 42
k = = =
y = x ← equation of variation
It is 31%.
To explain, you have to just have to multiply 0.31 by 100, and then add a percentage sign.
