Isn't it just
Mean = (total points of all the tests) divided by (number of tests) ?
Let's work with that.
Multiply each side of that formula by (number of tests), and you have
Total points of all the tests = (Mean) times (number of tests).
In this problem, you know the mean, and you know the number of tests,
so you can easily calculate the total points.
