Answer
The distance in a week is more than 720 miles.
Work Step by Step
Consider the given condition. It forms the equation as,
$80+\frac{25x}{100}>260$
Solve the above the equation.
$\begin{align}
& 80+\frac{25x}{100}>260 \\
& 0.25x>260-80 \\
& x>\frac{180}{0.25} \\
& x>720
\end{align}$
This shows that the Basic Rental will be a better deal than the Continental’s rental cost when car is driven for 720 miles.
Thus, the distance in miles that must be driven in a week is more than 720 miles.
