So  it seems you just can't bother reading/ understanding a simple request of using images/graphics huh?  This isn't complicated unlike the actual question. PLEASE RESPOND IN TEXT AND NOT IN IMAGES/GRAPHICS!!!  So again could you help me figure out part E with simple plain text...the characters you are literly are reading  instead of those stupid images. I know you can do it...other people have figured that part out.

You have stumbled on an unknown civilization while sailing around the world. The people, who call themselves Zebronians, do math using 40 separate characters (probably because there are 40 stripes on a zebra). They would very much like to use computers, but would need a computer to do Zebronian math, which would mean a computer that could represent all 40 characters. You are a computer designer and decide to help them. You decide the best thing is to use BCZ, Binary Coded Zebronian (which is like BCD except it codes Zebronian, not Decimal). How many bits will you need to represent each character if you want to use the minimum number of bits? Note: You must give proper reasoning on a sheet of paper.     5   3   4   6

please help me on this
