Suppose that y varies directly with x. Given x=4 when y=20.
Find y when x = 3

y = 15

Step-by-step explanation:

Given: y varies directly with x, x=4 when y=20

To find:  y when x = 3

Solution:

As y varies directly as x, it means that as x increases, y also increases by the same factor.

As y varies directly with x,

Here, k is a constant

As x = 4 when y = 20,

Put x = 3
