Question 250118
the equation for inverse variation is:


y = k/x


in your equation, it states that when y = 240, x = 23


you plug that into the equation to get:


240 = k/23


solve for k and you get k = 23 * 240.


k is your constant of variation.


when x = 30, the equation becomes.


v = k/30 which becomes:


v = 23 * 240 / 30 which becomes:


v = 184
