A biologist is developing two new strains of bacteria. Each sample of Type I Bacteria produces 16 now viable bacteria, and each sample of Type Il produces 25 new viable bacteria. Altogether, at least 550
new viable bacteria must be produced. At least 30 but not more than 50, of the original samples must
be Type I. Not more than 50 of the samples can be Type Il. A sample of Type I costs $10 and a sample
of Type Il costs $8. How many samples of each should be used to minimize cost?
