Answer:

It's irrelevant.

Explanation:

20 theater tickets cost 20T, 16 cinema tickets cost 16C.

Their sum is 20T+16C

You can factor a 4 out of this expression to get 4(5T+4C).

The two expressions are completely equivalent: there is no reason, in general, to prefer 20T+16C or 4(5T+4C).

Sometimes, the exercise may ask explicitly for the factored form.

In other cases, one of the two expression might be more useful: if you had to divide everything by 2, of course it's easier to write


(4(5T+4C))/(2) = 2(5T+4C)

If instead you had to subtract 10T, it would be more useful to write


20T+16C-10T = 10T+16C

To recap, 20T+16C and 4(5T+4C) are completely equivalent, and unless you have explicit requests, you may prefer one or the other depending on the calculations you have to do.
