Let Cameron be x years old now.
-
<u>Now:</u>
Cameron = x
Uncle =3x
-
<u>4 years ago:</u>
Cameron = x - 4
Uncle = 3x - 4
-
<u>4 years ago, Uncle is 4 times older:</u>
3x - 4 = 4(x - 4)
-
<u>Find x:</u>
3x - 4 = 4(x - 4)
3x - 4 = 4x - 16
4x - 3x = 16 - 4
x = 12
-
<u>Find the age:</u>
Cameron = x = 12

Answer: Cameron is 12 years old now.
Set up a ratio:
240/180 = X/36
Cross multiply:
240 * 36 = 180x
8640 = 180x
Divide both sides by 180:
X = 8640 / 180 = 48
The person would weigh 48 pounds.
I pretty sure the best answer would be f(x)=cbrt(27-x)
cbrt means cube root by the way.
