Answer 1

First, let's calculate the actual cost.

`239*6=1434` is the actual cost of six nights.
The formula for percent error is
`|(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:
`|(1434-1450)/(1450)|*100`

`|(-16)/(1450)|*100`

`|-0.0110344828|*100`

`0.0110344828*100`

`1.10344828%` is the percent error.
