To celebrate a colleague's retirement, the T coworkers in an office agreed to
share equally the cost of a catered lunch. If the lunch costs a total of x
dollars and S of the coworkers fail to pay their share, which of the
following represents the additional amount, in dollars, that each of the
remaining coworkers would have to contribute so that the cost of the lunch is
completely paid?
1.x/T
2.x/(T-S)
3.Sx/(T-S)
4.Sx/T(T-S)
5.x(T-S)/T
