The cell phone plan cost $39.99 per month plus $0.17 for each text message you send or receive. The maximum amount you have to spend is $47.

let

the number of text message you send or receive = x

Therefore,


\begin{gathered} 39.99+0.17x\leq47 \\ 0.17x\leq47-39.99 \\ 0.17x\leq7.01 \\ x\leq(7.01)/(0.17) \\ x\leq41.2352941176 \end{gathered}

The maximum number of text message he can send or receive is approximately 41 .
