Given:
x =30
y = 6
Find y, when x = 15
Solution:
In order to find y, when x = 15, we must first find the constant of variation of the given values, to do so, we simply multiply x and y.
k = xy
k = (30)(6)
k = 180
Equate 180 as k, 15 as x, then solve for y.
180 = 15y
Divide both sides by 15 in order to determine the value of y.
180/15 = 15y/15
y = 12
Final answer:
y = 12
