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:
We add them up and obtain the following: 4.25 and that's the hotel rating
4.25
What is Michael's score if he gets 79 on the first exam and 83 on the second, given that the weight of the first test is 30% and that of the second is 70%?
To solve the weighted average, we will use the following formula:
exam 2 * weight of evaluation 2 + exam 1 * weight of the evaluation 1 = Weighted average
We will place the data in the formula, where the weights will be in decimal numbers:
0.3*79 + 0.7*83 =
23.7+58.1 =
81.8

In order to determine the hotel rating, we will calculate an average.
Let's remember the weighted average formula:
(value A X weight percentage A)+(value B X weight percentage B)...
First, let's add all the percentages together to make sure we reach 100 percent:
Now we'll multiply each factor by its weight percentage, convert the percentages to decimal numbers, and add them as follows:
Let's solve the multiplication problems first:
We'll add them together and get: 3.475 and that's the hotel rating
