Ascientist is looking at 1000 germs under a microscope
andfinds that the germs double in number every 4 hours.
using,
how many germs will there be in 7 hours.

3500

Step-by-step explanation:

Number of germs that a scientist can see under a microscope = 1000 germs

We need to find how many germs will there be in 7 hours if the germs double in number every 4 hours .

It's given that the germs double in number every 4 hours .

So, increase in number of germs in one hour =

Increase in number of germs in seven hours =

Therefore , number of germs in 7 hours = Increase in number of germs in seven hours × Number of germs initially

=

So, number of germs in 7 hours if the germs double in number every 4 hours = 3500
