if i have a 79 in my math class and i take a test worth 12 percent toward my grade and i get a 72 what will my grade be

To calculate your new grade after taking the test worth 12 percent, you can use the following formula:

New grade = (Current grade * Current weight) + (Test grade * Test weight)

Given:
Current grade = 79
Current weight = 88% (100% - 12%)
Test grade = 72
Test weight = 12%

Plug in the values:

New grade = (79 * 88%) + (72 * 12%)
New grade = (69.52) + (8.64)
New grade = 78.16

Your new grade after taking the test worth 12 percent will be approximately 78.16.
