Weighted Average Calculation: Finding Hotel Rating from 50%, 30%, 10% Factors

In order to determine the hotel rating, we must calculate an average.

Below is the weighted average formula:

(value A X weight percentage A)+(value B X weight percentage B)...

First, let's add up all the percentages:

$50\%+30\%+10\%+10\%=100\%$

Now we must multiply each factor by its weight percentage, convert the percentages to decimal numbers, and add them as follows:

$4.5\times0.5+4\times0.3+5\times0.1+3\times0.1=$

We then proceed to solve the multiplication exercises:

$2.25+1.2+0.5+0.3=$

Finally we add them up and obtain the following: 4.25 which is the hotel's overall rating.
