The birth rate in an area is increasing 6% per annum. If there 20,000 children born in this area 2009 how many will be in 2018?

Step-by-step explanation:

Compound increase

20,000 x 1.06 to power of 9 = 33789 OR  33790

                  /\                        /\

               increase by 6%    9 years

well there are two answers for that.

1: you need 120 ones then that will equal up to 120.

2: you could also do one 100 and 2 tens.

those are the answers that i have thought of.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2  

x

2  

x

​    

=240

=48
