Show me the steps to solve

$4.)$ Assuming the picture below is to be stored using the Compression Ratio How many bits will it take with and without compressing it$.$ And what is the compression ratio?

This is my work so far:

$12$ x $10=120$ pixels

$120$ pixels x $1$ bits $=120$ binary digits

$($blue$,4)($green$,2)($red$,4)($blue$,4)($green$,2)($red$,4)($blue$,4)($green$,2)($red$,4)($blue$,3)($green$,4)($red$,3)($blue$,3)($green$,4)($red$,3)($blue$,3)($green$,4)($red$,3)($green$,7)($red$,3)($green$,7)($red$,3)($green$,13),($red$,3)($green$,7)($red$,3)($green$,7)($red$,3)($green$,4)$

I need to know what number to multiply my paranthese count $(29$ total$)$ in order to find the compressed data.
