A certain stock is worth x dollars per share at the beginning of a recent month. By the end of the first week of that month, the stock's value doubled, then decreased by 5 points (5$ per share). Express, in symbolic form, the total value of your stock at the end of the week if you own 60 shares.

Question

A certain stock is worth x dollars per share at the beginning of a recent month. By the end of the first week of that  month, the stock's value doubled, then decreased by 5 points (5$ per share). Express, in symbolic form, the total value of your stock at the end of the week if you own 60 shares.

Is the question stated correctly?  

It can't double by the END of the first week, then loss $5 per share.  Did it loss $5 per share over the weekend/night and open the next trading day $5 lower?

The stock could have doubled DURING the week and loss $5 per share by the END of the week.

Answer 1) as stated    Value of Stock  = 60 shares times 2 times the initial value at  end of the first week
                         Value = 60(2x)     the END o the first week as stated

Answer 2) what I think they want is   Value at end of week after it doubles and looses $5
                         Value = 60(2x -5)

I usually don't give answers but in this case of a poorly stated question I can't figure out which equation is correct.

My question is do you understand how I wrote the second equation?

I forget to state that x is the value of the stock at the beginning o the week / month.
