Are the Resistors in a Parallel Circuit and is 3.50 A the Total Current?

[Soaring Crane]

Homework Statement

In the circuit shown in the figure, the rate at which R1 is dissipating electrical energy is 20.0 W.

I just have questions about the circuit's setup. The resistors are arranged in a parallel circuit?

As for the purple arrows, is 2.00 A I_1 and 3.50 A the total current in the circuit?

Homework Equations

See below.

The Attempt at a Solution

This is just a preliminary question. I shall post my workings at a later time if I am baffled by the questions associated with the figure.

Thanks.

Yes, the resistors are in parallel.

As for the purple arrows, is 2.00 A I_1 and 3.50 A the total current in the circuit?

That's how I would interpret them.
