A cell phone plan costs $21.90 per month for 600 minutes of talk time. It costs an additional $0.08 per minute for each minute over 600 minutes. To get e-mail access, it costs 20% of the price for 600 minutes of talk time. Your bill, which includes e-mail, is the same each month for 6
months. The total cost for all 6 months is $188,88. Write and solve an equation to find the number of
minutes of talk time you use each month,
given situation?

please help!

hi,

6x times 4 is 24x and 5 times 4 is 20, so the answer is 24x+20.

hope this and for a little humor i am groot.

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
