# When y = 35, x=2 1/2. If the value of y directly with x what is the value of y when the value of x is 3 1/4?

Mar 8, 2018

Value of $y$ is $45.5$

#### Explanation:

y prop x or y=k*x; k  is variation constant

 y=35 ; x= 2 1/2 or x= 5/2 or x=2.5:. 35=k*2.5 or

$k = \frac{35}{2.5} = 14 \therefore y = 14 \cdot x$ is the variation equation.

$x = 3 \frac{1}{4} \mathmr{and} x = 3.25 \therefore y = 14 \cdot 3.25 \mathmr{and} y = 45.5$

Value of $y$ is $45.5$ [Ans]
