The value of y varies directly with x, when x=1/4, y=25. What is the value of y when x = 2 1/3

The answer is that y = 233.33

Step-by-step explanation:

In order to find the value of y in the later example, we first need to find the direct variation equation. We can find this by using the base form of the equation and finding k.

y = kx

25 = k (*1/4)

100 = k

Now model the equation. And input x into the equation.

y = 100x

y = 100 (2 1/3)

y = 233.33
