Aparent increases a child's monthly allowance by 20% each year.
if the allowance is $8 per month now, in about how many years will
it take to reach $20 per month? use the equation 20 = 8(1.2)* to
solve the problem. round to the nearest year.

no one knows lol

step-by-step explanation:

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
