1. The farmers in Ravin's town complained about the lack of rain during the growing
season. Ravin did some research to find out
how much rain typically falls during the
growing season compared to the amount of
rain during this growing season. She
learned that it had rained 7 inches less than
normal this season. Write an expression
that represents the amount of rain this
growing season.
n-7

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

x

​    

=240

=48
