The manager of a sporting goods store instructs her employees to greet at least 80% of customers who enter the store. Each day, approximately 250 customers visit the store. An employee decides that, to comply with the manager’s directive, he must greet at least 170 customers each day as they enter the store. The employees calculations are: 250 – 80 = 170

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}
