HELP ASAP PLZ Bill is purchasing accordion lessons. There is a $20 materials fee and each lesson costs $15. Write an equation for this situation AND determine how many lessons Bill took, if his total cost was $125.

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
