Determine the hotel's overall rating?
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:
Now we must multiply each factor by its weight percentage, convert the percentages to decimal numbers, and add them as follows:
We then proceed to solve the multiplication exercises:
Finally we add them up and obtain the following: 4.25 which is the hotel's overall rating.

Because the categories have different levels of importance! Satisfaction counts for 50% while Service only counts for 10%. A weighted average gives more influence to the more important categories.
Simply divide by 100 or move the decimal point two places left. For example: 50% = 50 ÷ 100 = 0.5, and 10% = 10 ÷ 100 = 0.1.
Always check that your weights sum to 100% first! If they don't, there might be missing categories or an error in the problem. In this case: 50% + 30% + 10% + 10% = 100% ✓
The percentage tells you how much each category contributes to the final rating. Multiplying means Satisfaction contributes 2.25 points to the overall rating.
Yes, but it's trickier! You'd calculate . Converting to decimals first is usually easier and less error-prone.
