Given Problem Information
| Parameter | Value |
|---|---|
| Current Grade | 77% |
| Target Grade | 80% |
| Remaining Project Weight | 20% (0.20) |
Step-by-Step Calculation
Determine points secured
77 \times 0.80 = 61.6\text{ points}Points secured from 80% of coursework.
Find deficit to target
80 - 61.6 = 18.4\text{ points needed}Point gap to fill on project.
Divide by project weight
18.4 \div 0.20 = 92.0\%Required score on final project.
Final Solution Outcome
