Homework Statement
I'm just trying to calculate Ix using the current divider law.

Homework Equations
Ix = I_total * (R_total / R_x)
The Attempt at a Solution
I've had an issue with the voltage & current divider law for a while. They seem to require some common sense which I'm lacking.
Anyway, I know that I can find the total current by condensing the circuit down to the voltage source and a single resistors. I_total = 10 A.
The tricky part for me is figuring out what R_total and R_x equal. I've always assumed that R_total is the resistance of the entire circuit while R_x is the resistance of the item in question (in this case the 80 ohm resistor).
I'm not getting the correct answer based off of my work, so any help would be appreciated.
