Question 391939

If all the workers contributed, each would contribute y/m dollars.  But since P of the coworkers failed to contribute, then each of the remaining coworkers contributed y/(m-p) dollars.  So we have:
(y/(m-p))-y/m)=the additional amount that each would have contribute
Simplifying we get: (multiply numerator and denominator of each term by m(m-p)
(ym-y(m-p))/m(m-p)=
ym-ym+yp/m(m-p)=
yp/m(m-p)
