Answer:  Cindy can withdraw $30 for 5 months without paying service fees.

Step-by-step explanation:  Given that Cindy deposited $350 into a savings account. As long as the account balance remains at or above $200, she does not have to pay a service fee for the account.

We are to find the time for which she can withdraw $30 a month without paying service fees.

Let x represents the required number of months.

According to the given information, we have

[tex]x\times30\leq 350-200\\\\\Rightarrow 30x\leq 150\\\\\Rightarrow x\leq\dfrac{150}{30}\\\\\Rightarrow x\leq5.[/tex]

Therefore, Cindy can withdraw $30 for 5 months without paying service fees.
