PLEASE HELP WITH!

Antonio is working on programming a new video game called
Millie’s Quest. In the game, the main character, Millie, collects golden
keys to help her in her quest. Antonio wants to write a formula to
show that Millie can collect one less key than the highest number of
bits that can be arranged in the system. What formula can he use?

b. If Antonio is working with a 16-bit system, how many golden keys
can Millie collect?

c. Antonio is also working on a new spreadsheet program. The
program takes up 14 bytes of memory. If each byte is equal to 8 bits,
how many bits is Antonio’s program? Show your work.
