A certain kind of bacteria multiplies at a rate of 150 percent per hour. When a person’s blood has 45,000,000 of these bacteria, the person will fall sick. Let’s suppose 100 such bacteria entered a person’s blood. How many hours will it take for the person to become sick? Arrange the steps in the right order to show how to find the number of hours it will take for the person to fall sick.
45,000,000 = 100(1 + 1.5)t
450,000 = (2.5)t
log 450,000 = t log(2.5)
45,000,000 = 100(2.5)t

log 450,000 = log(2.50)t

14.21 hours = t
