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
