Researchers recorded that a group of bacteria grew from 200 to 1,000 in 8 hours. at this rate of growth, how many bacteria will there be in 20 hours from the start of the experiment? round to the nearest whole number.

2000 bacteria

Step-by-step explanation:

Given the bacteria grew from 200 to 1,000 in 8 hours

The rate of growth =

Here bacteria growth = 1000 - 200 = 800

Number of hours = 8 hours

The rate of growth = bacteria per hour

Let us assume that at the start of the experiment the number of bacteria be 0

Given the time = 20 hours

The bacteria growth = the rate of growth the time

bacteria after 20 hours - bacteria initially = bacteria

Bacteria after 20 hours = 2000

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
