Neco Model Questions Vol1 2022 Civic Education Question 16

A citizen's overall civic contribution score \(S\) is calculated as \(S = 5V + 2C + 3T\), where \(V\) is the number of elections voted in during a five‑year period (maximum 5), \(C\) is the total number of community‑service days completed in that period, and \(T\) is the tax‑compliance rating (an integer from 0 to 10). The citizen has already voted in 3 elections and currently has a tax‑compliance rating of 8. They may improve their tax rating by attending tax‑workshop sessions; each additional point in \(T\) requires 2 days of community service that could otherwise be counted as service days. To achieve a minimum score of 100, what is the minimum number of community‑service days the citizen must actually perform (including any days used to raise \(T\))?
