Sickly Sid has contracted a serious infection and has gone to the doctor for help. The doctor takes a blood sample and finds 900 bacteria per cc
(cubic centimeter) and gives Sid a shot of a strong antibiotic. The bacteria
will continue to grow for a period of time, reach a peak, and then decrease
as the medication succeeds in overcoming the infection. After ten days,
the infection has grown to 1600 bacteria per cc. After 15 days it has grown
to 1875. What are the three ordered pairs that would help us write
equations to solve this problem? *
