Ok so we know that in the first quarter the company sold 125000 units to people. But then suddenly they start losing 5%. Since we are told there are 3 quarters, we would have to do 5% plus 5% plus 5%, which amounts to 15% total lost in the three quarters. What we do now is we technically subtract that to 125000, so the equation would be 125000 minus 15%, and when you either use a calculator to help or your own mind, you get 106250 units sold.
