Answer 1

```
int main()
{
char grade; // grade desired
double minpercent, // minimum average required for that grade
currentave, // current grade average
finalpercent; // % of the total score the final is worth
cout << endl << "Enter desired grade=> ";
cin << grade;
cout << "Enter minimum average required for a " << grade << "=> ";
cin << minpercent;
cout << "Enter your current average in the course=> ";
cin << currentave;
cout << "Enter how much the final counts as a percentage" << endl
<< "of the course grade=> ";
cin << finalpercent;
double finalfract = finalpercent / 100.0;
double needed = (minpercent - currentave * (1.0 - finalfract))
/ finalfract;
cout << endl << "You need a score of " << needed
<< " on the final to get a " << grade << "." << endl << endl;
return 0;
}
