A report by the Government Accountability Offi ce (GAO) shows that the GAO expects the U.S. Postal Service to lose a record $ 2.5 billion at the end of this year, and if the business model is not changed, the losses will total $ 135.2 billion by the end of year 10. If the losses increase uniformly over the 10-year period, determine the loss (in billions) only in year 5 from now
