frankie has an avg of 57% and he has 2 test left worth 5% each and 1 assigment worth 1% and 2 assigment both 2% how much would he need to bring his avg to 80?

say that all the test are out of 60 marks

MS SUE WHAT DO U MEAN BY THIS?"It makes a huge difference whether the total marks (points) for the class is 600 or 6,000." the test are all out of 60 marks what else do u need?

As I understand your question, Frankie has earned an average of 57% of a certain number of points. With assignments and tests together, let's say that at this point there have been 600 points in this class. So -- 57% means that he has earned 342 points.

I don't understand what you mean by saying that the combined tests and assignments he has left total 15%.

15% of what?

Please ask your teacher to clarify this problem.

this is supposed to be a real life sceneraio

there are 2 test worth which are worth 5% each of his overall mark. Then there is 1 assigment worth 1% of his over all mark. Also he has 2 test worth 2% of his overall mark.

Before all this overall mark is 57%. THis is due to all his assigment and test that he has done before.

All future test are out of 60 marks

I apologize for any confusion caused by my previous statement. Since the tests are out of 60 marks, we can assume that the total marks for the class are 600 in this case.

To determine how much Frankie would need to bring his average to 80%, we can follow these steps:

Step 1: Calculate the current total weightage of all the completed assessments.
- Current average = 57%
- Total weightage of completed assessments = (2 tests worth 5% each) + (1 assignment worth 1%) + (2 assignments worth 2% each)
- Total weightage = (2 * 5%) + 1% + (2 * 2%) = 10% + 1% + 4% = 15%

Step 2: Determine the remaining weightage needed to achieve an average of 80%.
- Desired average = 80%
- Remaining weightage needed = Desired average - Current average
- Remaining weightage needed = 80% - 57% = 23%

Step 3: Distribute the remaining weightage across the two tests and three assignments.
- Since each test is worth 5%, distribute the remaining weightage equally between the two tests.
- Remaining weightage for the tests = 23% / 2 = 11.5%
- Since each assignment is worth 2%, distribute the remaining weightage equally among the three assignments.
- Remaining weightage for each assignment = 23% / 3 = 7.67%

Therefore, Frankie would need to score an additional 11.5% on each of the two remaining tests and an additional 7.67% on each of the three remaining assignments to bring his average to 80%.
