Question

The population of bacteria doubles every 6 hours. By how much will it grow in three days. Write the equation

Answer 1

Explanation:

let x be the population

so we have ,

2x= 6h

?= 3 days or 3×24h

by cross multiplication we have

2x× 72h= 6h×?

?= 2x×72/6 = 24x

So, in three days the bacteria will b 24 times current population.
