PLEASE help me solve this question! No nonsense answers please!

Answer 1

`\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.
