Answer:  The opening price of the stock at the beginning of the day = $31.

Step-by-step explanation:

Given, The stock of Company A lost 2% today to $30.38.

So,

Closing price = $30.38.

Also as per given, Opening price - 2% of Opening price = $30.38.

⇒ Opening price x (1-0.02) = $30.38   [∵2%=0.02]

⇒ Opening price x (0.98) =  $30.38  

⇒ Opening price = ($30.38  ) ÷ (0.98)

Opening price = $31

Hence,  the opening price of the stock at the beginning of the day = $31 .

The opening price of the stock was $31.

How to find the opening price?

The opening price will represent the 100% in this case, so if we say that the opening price is P, we can write:

P = 100%

Now we know that after a decrease of 2%, the new price is $30.38, so we can write:

$30.38 =  98%

Taking the quotient of these two equations, we get:

P/($30.38) = (100%/98%)

Solving for P we get:

P = ($30.38)*(100%/98%) = $31.00

the opening price was $31.
