If the number of bacteria in a colony doubles every 18 minutes and there is currently a population of 500 bacteria, what will the population be 72 minutes from now?

8000 plz mark brainliest

Step-by-step explanation: 72/18 =4 (therefore it doubles 4 times as shown below)

500*2=1000

1000*2=2000

2000*2=4000

4000*2=8000

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
