A bacteria triples every 35 minutes. There were 50 bacteria initially. How many bacteria will be present after 3 hours? A radioactive isotope decays rapidly with a half-life of 4 minutes. For a 12 minute test, technicians need at least 6 grams of the isotope to remain at the end of the test. How much must they start with? The amount of sunlight a diver can see is halved for every 11 m she dives. What percentage of light remains when the diver is 60 m below the surface? The University of McMaster undergraduate program is growing at a rate of 3% each year. The current enrollment is 12400. Determine when the enrollment will reach 13250. You have found an investment at the bank that pays 2.4% interest per year for 10 years. How much should you invest now so that you have $2000 at the end of the 10 years?
