A stock loses 10% of its value on Monday. On Tuesday it loses 20% of the value it had at the end of the day on Monday. What is the overall percent loss in value from the beginning of Monday to the end of Tuesday?

Call the value  before Monday's loss, V

After Monday...the stock is worth .90V

After Tuesday, the stock is worth  .80 (.90V)  = .72V

So....it loses  1  - .72  =    28% of its value

100% - 10% =90%

90% x (100 -20)= 72%      

100 -72= 28% loss from original value.
