Question

A culture of yeast doubles in size every 4 hours. If the yeast population is estimated to be 3 million now, what will it be one day from now

Answer 1

192,000,000

Explanation:

Given

General form of an Exponential distribution :

y = ab^x

a = initial amount = 3000000

b = growth factor = 2

x = period = 24 / 4 = 6

y = final amount ; after one day = 24 hours ; x = 24 /4 = 6

y = 3000000(2)^6

y = 3000000 * 64

y = 192,000,000
