Find the current in each resistor.
Find the power delivered by the battery.

Homework Equations

V=I/R
P=IV

The Attempt at a Solution

Now I feel like this problem is ridiculously simple, but cannot seem to get it right.
At first, I felt like all I needed to do was plug in the resistance and voltage of the battery, and that would give me the answer. But the resistors are in series/parallel with each other, and I know that affects the current but I'm not really sure how...

Thanks for the help I really appreciate it. I know this is a really simple problem I just can't seem to get it right...

You'll have to find out how to combine series and parallel resistances before you go on. Then you should identify what's in series or parallel in the given circuit.

I suggest you first find the total equivalent resistance of the resistor network, and hence the current being delivered by the battery. After that, the things you need to determine will start to emerge/unravel from the circuit.
