Answer:

$\boxed{\sf Option \ 1}$

Explanation:

The profit is revenue (R ) - costs (C ).

Subtract the expression of costs (C ) from revenue (R ).

10x-0.01x^2-(2x+100)

Distribute negative sign.

10x-0.01x^2-2x-100

Combine like terms.

8x-0.01x^2-100

The first option has a positive 100, which is wrong.

The rest options are right, when we expand brackets the result is same.
