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