How do you set up a proportion or percent bar to solve this problem? at a local amusement park, 70% of the rides are made for kids who are 48 inches or taller. if there are 80 rides in total, how many are made for kids who are 48 inches or taller?

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
