Question

If I have a 62% in a class, what percentage do I need to get on a 50% weighted test grade to have at least a 70% in the class?

Thank you :)

Answer 1

78%

Explanation:

70 = 0.50 (62) + 0.50 (x)

70 = 31 + 0.5x

39 = 0.5x

x = 78

You must get at least a 78% on the test to have at least 70% in the class.
