Question

My grade is 92 if an assignment is worth 40% of my grade what will my grade be if I got a 0, 25, and a 50?

Answer 1

If you get a 0 on your assignment, your grade will be (92 * 0.6) + (0 * 0.4), which will give you a final grade of 55.2%

If you get a 25 on your assignment, your grade will be (92 * 0.6) + (25 * 0.4), which will give you a final grade of 65.2%

If you get a 50 on your assignment, your grade will be (92 * 0.6) + (50 * 0.4), which will give you a final grade of 75.2%

If you get a 75 on your assignment, your grade will be (92 * 0.6) + (75 * 0.4), which will give you a final grade of 85.2%

If you get a 100 on your assignment, your grade will be (92 * 0.6) + (100 * 0.4), which will give you a final grade of 95.2%

Answer 2

0: 
92 times 0.6 + {0 times 0.4} =  55.2
So your grade would be a 55.2%, which is an F. 

25:
92 times 0.6 + 25 times 0.4 = 65.2
So, your grade would be a D, or 65.2%

50:
92 * 0.6 + 50 * 0.4 = 75.2
Giving you a grade of 75.2, which is a C. 

75:
92 * 0.6 + 75 * 0.4 = 85.2
So your grade would be a 85.2% which is a B. 

My advice to you: Aim for an A+. :)
