Question

Maria, a biologist, is observing the growth pattern of a virus. She starts with 100 of the virus that grows at a rate of 10% per hour. She will check on the virus in 24 hours. How many viruses will she find? Round your answer to the nearest whole number.

Answer 1

Answer:

Initial virus = 100 at 0.1/hr

100×0.1 = 10virus/ hr

24hrs=?virus

10 virus = 1hr

? = 24 hrs

The number of virus at 24hrs= 240virus ×hr/1 hr

=240 virus.

Answer 2

Answer: 985

=============================================

Work Shown:

A = amount after t hours

P = initial amount = 100

r = growth rate in decimal form = 0.10

t = number of hours = 24

--------

A = P*(1+r)^t

A = 100(1+0.10)^24

A = 100*(1.10)^24

A = 100*9.84973267580762

A = 984.973267580762

A = 985
