I am stuck on this circuit. I cannot seem to find the total current of it. How would I do it?

No. Let's take a look at why.The forward voltage of the diode is 1.7v and the voltage source voltage is 5v. Couldn't it be solved with 5/(((5-1.7)/0.1+5/0.1)+0.1)?
Let's label the three resistors Ra, Rb, and Rc from top to bottom. Let's call the currents in them Ia, Ib, and Ic with the direction coming from the positive side of the battery toward the negative side.. For the voltages, let's call the node at the bottom of the battery GND (0V), the voltage at the top of the battery V0, and the voltage at the remaining node (the top of Rc) V1. Finally, let's call the forward voltage drop across the LED Vf.How would I find the voltage across the parallel resistors when the bottom resistor affects the voltage and current within them?
How did you arrive at this?With the LED removed there is 2.5v across the top resistor and 25mA.
