There are 12 inches in a foot, and 3 feet in a yard, so there are 36 inches in one yard which means that yards = inches/36. So the answer should be:

<span>f(n) = n/36</span>

The answer is $f(n)= \frac{1}{36} n$

Hi,
To find K you will pick a value from the x and then the corresponding Y value. Then we will plug it into the equation that is given y=Kx

Here:
X=25 Y=160
160=k25
(Divide both sides by 25 to isolate K)
K=6.5

Then plug K value into equation
Y=6.5X

Then if you want to check if that is correct you can pick a different point on the table and plug that into the equation to see if you get the same value.

Check:
X=50

Y=6.5x50
Y=320
