Question

Leo made a 59, 84, 61, and an 81 on the first four tests. What score

would he have to make on the 5th test in order to make at least an 85
in the course?

Answer 1

71

Explanation:

59 add 84 add 61 add 81 is 285

285 divided by (how many test scores) 4 is 71.25

I then rounded the number to 71. So leo would get 71. This is called mean. The mean is basically adding all the numbers then dividing it by how many there were of numbers. Mean tells you the average. So I'm pretty sure it's 71.
