3. Lake City Jr. High Students: *** 12 out of every 18 ride a bus to school

*** 9 out of every 15 live in Lake City

*** 160 ride a bus to school

How many of the Jr. High students do not live in Lake City?

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}
