First, let's calculate the actual cost.
$239*6=1434$ is the actual cost of six nights.
The formula for percent error is $|\frac{measured value-accepted value}{accepted value}|*100$
The bars (|) stand for absolute value which gets rid of the negative sign if there is one.
Plug in the values: $|\frac{1434-1450}{1450}|*100$
 $|\frac{-16}{1450}|*100$
 $|-0.0110344828|*100$
 $0.0110344828*100$ 
 $1.10344828%$ is the percent error.
