1201 100 | c | = | ( | 17 5 | + | c | ) | × | 399 50 |
| Right side of the equation = | 17 5 | × | 399 50 | + | c | × | 399 50 |
| = | 6783 250 | + | c | × | 399 50 |
1201 100 | c | = | 6783 250 | + | 399 50 | c |
1201 100 | c | − | 399 50 | c | = | 6783 250 |
403 100 | c | = | 6783 250 |
| c | = | 6783 250 | ÷ | 403 100 |
| = | 6783 250 | × | 100 403 |
| = | 6783 5 | × | 2 403 |
| c | = | 13566 2015 |
| c | = | 6.732506 |
