Karen works for $6 an hour. a total of 25% of her salary is deducted for taxes and insurance. she is trying to save $450 for a new car stereo and speakers. how many hours must she work to take home $450 if she saves all of her earnings?

you can't solve x because it is 2 linear equation and you only have one equation

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

=240

=48
