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.

Best ResponseYou've already chosen the best response.2okay. do you have any answer choices, or no? and did you attempt to solve it yet?

Best ResponseYou've already chosen the best response.0I do have choices, but I don't know how to solve it with steps. I don't want to just generate it from a calculator... I wanna know how to do it.

Best ResponseYou've already chosen the best response.2The only real way possible is to solve using a calculator, but I will show you how the steps work

Best ResponseYou've already chosen the best response.2first thing you will do is divide the 15500 from both sides so:dw:1440807637374:dw

Best ResponseYou've already chosen the best response.2okay, now is where your graphing calculator comes in. you must use the function (ln) to solve.

Best ResponseYou've already chosen the best response.2so \[\ln \left( 30000/15500 \right) = .66\]

Best ResponseYou've already chosen the best response.0I don't have a graphing calculator on me right now but I understand

Best ResponseYou've already chosen the best response.2okay good :) then you move on to the other side and use \[\ln (1.18) = .166\]

Theloshua

Best ResponseYou've already chosen the best response.2so now you have \[.66 = .166x\]

Best ResponseYou've already chosen the best response.2so? how do you do that?

Best ResponseYou've already chosen the best response.0I would do 66/100 166/100 x so 2*3*11/2^2*5^2 2*83/2^3*5^3 x 330/83 which is like 3.975 ish

Best ResponseYou've already chosen the best response.0so my answer would be 4

Best ResponseYou've already chosen the best response.2you got the answer, but whatever you did was super complicated

Best ResponseYou've already chosen the best response.0well that's how my book has others solved for x, but I mean I still got the answer. It makes sense to me

Best ResponseYou've already chosen the best response.0You way is simpler so I'll use that way too

Best ResponseYou've already chosen the best response.0sorry what it that number under the 1st . 66 ?

Best ResponseYou've already chosen the best response.2okay haha, yeah, whenever the equation is set up like that it is easiest to just divide both sides by the number with the variable. it instantly gives yoy your answer

Theloshua

Best ResponseYou've already chosen the best response.2yes, .166 both sides are divided by the number with the variable attached to it
