Mandy had three Maths tests and her mean mark is 84.What is the total of Mandy's marks for the three test?

3*84

yes

To find the total of Mandy's marks for the three tests, we need to use the concept of the mean. The mean is calculated by adding up all the individual scores and then dividing by the number of tests.

Let's assume Mandy's scores for the three tests are x, y, and z. We know that the mean mark is 84.

So, we can write the equation:

(x + y + z) / 3 = 84

To find the total of Mandy's marks, we need to solve this equation.

First, we can simplify the equation by multiplying both sides by 3:

(x + y + z) = 84 * 3

(x + y + z) = 252

Therefore, the total of Mandy's marks for the three tests is 252.
