Help me please with these matrices!

Okay, so I'm trying to figure this out on my own, since my teacher did nothing in the way of explaining it, but I just can't figure out how to set up what these problems are asking. If you could please at least give me an example for the first one I'd be so much less stressed out.

To show a 2% increase, simply multiply each element of the matrix by 1.02.
