$32.$ Coding Messages. Your friend has coded a meeting spot using the standard code a$=1,$ b$=2,$ c$=3$ etc.

To make the code more secure $($he doesn$$t want everyone to know where you are meeting$)$ he disguises

the message using matrix multiplication. Your friend uses the matrix A below to encrypt his message

A $=$

$2$

$64$

$121$

$253$

$232$

$3$

$75$

and you receive the message as

C $=$

$2$

$64$

$206248$

$49163115$

$3210582$

$3$

$75$

$.$

If the message was originally entered down the column of the matrix, where are you meeting your

friend?
