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.
