Question

When the value of yberries directly with x when y equals 75 x equals 1/2 what is the value of y when x is 2 and 1/4

Answer 1

337.5

Explanation:

direct variation means y=kx (inverse variation is yx=k or y=k/x)

so we are given that:

75=k/2, so k=150 which means:

y=150x now

y(2.25)=150(2.25)=337.5

Hope this helps
