<h2>34</h2>

Step-by-step explanation:

   The minimum charges for the phone service is $35. For, each text message, $0.50 is charged over and above the minimum charges.

   This problem can be modeled as a linear equation in the number of text messages sent as follows:\textrm{Total bill = Minimum charges + (Charge per message)x(Number of messages)}

\textrm{Total Bill = $}35\textrm{ + (Number of messages)x}($0.50)

   Given that the total bill is $52, number of text messages can be easily computed.

52\textrm{ = }35+\textrm{(Number of messages)x}0.50

\textrm{(Number of messages)x0.50 = }52-35=7

\textrm{Number of messages = }\frac{7}{0.5}=14

∴Number of text messages Juan sent = 14.
