Random audio assistance/advice requested: Adding a wireless mic to a crappy PA system

My boss told me to buy a cheap PA system for use at our office:

Then 3 days later decided she wants a wireless lapel mic for it.
WTF, how does one just add a wireless mic.

Best option I could find was http://www.zzounds.com/item--GXYECDRHHBPV
Does someone who knows anything about audio equipment know if that system will be likely to work with the PA system?
Have no idea how the two would be connected.

Thanks!

 

What kind of PA system?

Does it have mic inputs with XLR inputs or 1/4"TRS?

Those would be professional balanced inputs.

I am guessing it is a mono 1/4" consumer mic input you are looking to use though.

 

The PA linked above, it appears to have a mic input?

I assume I'll need to buy some sort of cable to connect the wireless unit/receiver to the PA but I've got no clue.

 

Sorry one selfish up and I'm done.
