Please only post your questions once. Repeating posts will not get a quicker response. In addition, it wastes our time looking over reposts that have already been answered in another post. Thank you.
I seems like you don't like the previous answer. With the data you presented, I agree with the previous answer. Could it be that you have additional data that might change our minds?

where is the previous answer?i have not posted it up twice, this is the first time i have posted this up
could u please direct me to where it is answered bfr?
To calculate how much Frankie would need to bring his average to 87%, we will need to consider the weights of the assessments and the desired average. Here's what we can do step by step:
1. Determine the current total weight of Frankie's assessments:
- Each test is worth 5%, so the total weight for the two tests is 2 * 5% = 10%.
- Each assignment is worth 3%, so the total weight for the two assignments is 2 * 3% = 6%.
- The remaining assignment is worth 1%.
2. Determine the total weight of all assessments:
- This will be the sum of all the individual assessment weights: 10% + 6% + 1% = 17%.
3. Determine the current total weight of Frankie's average:
- The current average is 57%, and it has a weight of 100% since it represents the entire grade up to this point.
4. Determine the desired average weight:
- Frankie wants to achieve an average of 87%, so this will have a weight of 100%.
5. Calculate the remaining weight needed:
- The remaining weight needed to achieve the desired average is the difference between the desired average weight and the current average weight: 100% - 57% = 43%.
6. Distribute the remaining weight among the remaining assessments:
- As there is 17% total weight available for the remaining assessments, we need to adjust their weights accordingly to reach the remaining weight needed of 43%.
- Let's assume the remaining assignment will be worth x%.
- The two remaining tests are worth 5% each, so their combined weight is 2 * 5% = 10%.
- The three remaining assignments, including the one worth x%, should have a combined weight of 17% - 10% = 7%.
7. Set up an equation and solve for x:
- We can now set up an equation to find the value of x: 3% + 3% + x% = 7%.
- Combining like terms: 6% + x% = 7%.
- Subtracting 6% from both sides: x% = 7% - 6% = 1%.
- So, the remaining assignment should be worth 1%.
Therefore, Frankie would need to score 100% on the remaining assignment worth 1% to bring his average to 87%.
