| p | = | 100 | ÷ | ( | 1 | + | 7 200 | ) | − | ( | 1 | ÷ | 2 | ) |
| Multiply both sides of the equation by: | ( | 1 | + | 7 200 | ) |
| p | ( | 1 | + | 7 200 | ) | = | 100 | − | ( | 1 | ÷ | 2 | ) | ( | 1 | + | 7 200 | ) |
| p | × | 1 | + | p | × | 7 200 | = | 100 | − | ( | 1 | ÷ | 2 | ) | ( | 1 | + | 7 200 | ) |
| p | × | 1 | + | p | × | 7 200 | = | 100 | − | 1 | ÷ | 2 | × | ( | 1 | + | 7 200 | ) |
| p | × | 1 | + | p | × | 7 200 | = | 100 | − | 1 2 | ( | 1 | + | 7 200 | ) |
207 200 | p | = | 100 | − | 1 2 | ( | 1 | + | 7 200 | ) |
207 200 | p | = | 100 | − | 1 2 | × | 1 | − | 1 2 | × | 7 200 |
207 200 | p | = | 100 | − | 1 2 | − | 7 400 |
207 200 | p | = | 39793 400 |
| p | = | 39793 400 | ÷ | 207 200 |
| = | 39793 400 | × | 200 207 |
| = | 39793 2 | × | 1 207 |
| p | = | 39793 414 |
| p | = | 96.118357 |
