Explanation:

Givens

• Mark has been watching 16 movies per month.
• Max has been watching half movies than Mark per month.
• They have seen 144 movies.

We can represent the number of movies Mark has been watching per month as

`Mark=16x`

The representation for Max is

`Max=(1)/(2)16x=8x`

Now, we know that they watched 144 movies in
`x` months, so

`16x+8x=144`

Then, we solve for
`x`

`16x+8x=144\\24x=144\\x=(144)/(24)=6`

Therefore, after 6 months, they watched 144 movies.
