The proportional relationship involving c and b is c ∝ b. The solution to c is c = kb (where k is constant)
Variation is a mathematical notion that relates to variability. Variation is defined to be any change in one quantity as a result of a change in another. Variation questions feature relatively basic connections or formulae in which one variable equals one term.
From the given question
A direct variation is a type of variation in which an increase in one term increases the other term as well, and, vice versa.
Let assume the proportional relationship follows a direct variation.
Then,
c ∝ b
The solution to c is:
c = kb
(where k is the constant)
