Mental Mathematics in Desicion Making
Rounding Off: In a certain multi-million
dollar company, Division Managers are required to submit monthly detail
and summary expense reports on which the amounts are rounded, for
ease of reading, to the closest $1,000. One month, a Division Manager's
detail report shows $1,000 for printing and $1,000 for copying. In
the summary report, the total for "printing and copying" is listed
as $3,000. When questioned about it by the Vice President, he claims
that the discrepancy is merely round-off error. In subsequent months,
the Vice President notices that such round-off errors seem to happen
often on this Division Manager's reports. Before the Vice President
asks that the Division Manager re-create the reports without rounding,
she wants to know how often this should happen.
