The formula for direct variation is y=kx where k is constant. Next, you have to lay out a formula for each of these scenarios

A) Since distance = rate x time, this is 150 = xy

B) Total pay = hourly rate x number of hours worked, this is 300 = xy

C) Total pay = number of cars you wash x rate per car, this is y = 10x

D) Area = length x width, this is 24 = xy

**The one in the correct form for direct variation is C**
