You invest $1,000 in a fund. you check your statement at the end of april and you have lost 13%. when the statement for may comes, you see you have gained 13% in may. what is the value of your account? round to the nearest dollar. a) $850 b) $917 c) $983 d) $1,057

Your loss of 13% means the value of the fund has been multiplied by
  100% - 13% = 87% = 0.87
Your gain of 13% means the value of the fund has been multiplied by
  100% + 13% = 113% = 1.13

Over the 2-month period, your fund's value has been multiplied by the product of these, so is
  $1000·0.87·1.13 ≈ $983.10

The appropriate choice is ...
  c) $983

What do you mean by that?
