Suppose the population in a town has an average growth rate of 18% . if there are 15,500 people now living in town, in about how many years will the population grow to 30,000? use the equation 30,000 = (15,500)(1.18)x and round the value of x to the nearest year.

Option C. 4 years

Step-by-step explanation:

Population growth of a town is described by the equation

where x is the number of years.

Now we have to calculate the duration after which population of the town will be 30000 with an average growth rate of 18%.

We will use the equation to get the value of x.

Now we take log on both the sides of the equation.

Log(1.94) = xlog(1.18)

0.2878 = .0719x

Therefore after 4 years population of the town will be 30000.

i get you, what you should do is think of the positive things that would come out of it. it will make yours parents proud and raise your grade. you should always try and if you can't focus tell the teacher.

i'm assuming that it's c.)   volcanoes built the mountains and earthquakes tore them down.
