a miracle ?

To determine how much Frankie would need to bring his average to 80%, we can break down the calculations for each component:

1. Current Average: Frankie's current average is 57%.

2. Tests: Frankie has 2 tests left, each worth 5% of his overall grade. Since each test is out of 60 points, the total percentage for tests is (avg_test / max_test) * weight_test, where avg_test is the average of the remaining test scores, max_test is the maximum possible score for each test, and weight_test is the weightage assigned to each test. In this case, avg_test = max_test because he hasn't taken the tests yet.
So, the contribution from the tests is (60 / 60) * 5% = 5%.

3. Assignments: Frankie has 1 assignment worth 1% and 2 assignments worth 2% each. Since he hasn't taken these assignments yet, the calculation will be the same as the tests. The contribution from these assignments is (0 / 60) * (1% + 2% + 2%) = 0%.

4. Remaining Average: Now we need to calculate how much Frankie needs on the remaining tests and assignments to reach an average of 80%. Let's call this value x. We can use the formula:
(Current Average + Contribution from Tests + Contribution from Assignments + Remaining Tests/Assignments) / Total Weight = Target Average
(57 + 5 + 0 + x) / (5 + 1 + 2 + 2) = 80%
(57 + 5 + x) / 10 = 80
62 + x = 800
x = 738

So, Frankie would need to score a combined total of 738 points on the remaining tests and assignments to bring his average to 80%.
