**Anonymous**, Wednesday, September 26, 2007 at 5:19pm70 - 2t, where t is the time in days (in this case, 5). That would give you an answer of 60 psi. (psi = Pounds per Square Inch)

A more accurate formula would take into account that the leak rate is proportional to tire pressure. They probably don't expect you to know that, since that involves physics.

The more accurate formula would be

70 *(68/70)^5 = 60.56 psi
