-1.2% -_- APEX

Explanation:

Answer 2

Answer: A. –1.2%

Explanation:

Since, the initial sum of the stocks = $ 10,335.24

While, the final sum of the stocks at the end of the day = $ 10,215.78

Thus, the percentage change in the sum of stocks

=
`\frac{\text{Final sum - intial sum}}{\text{ Final sum}}* 100`

=
`(10,215.78 - 10,335.24)/(10,335.24)* 100`

=
`(-119.46)/(10,335.24)* 100`

=
`-(11946)/(10335.24)`

=
`-1.15585124\% \approx -1.2\%`

⇒ Option A is correct.
