500 | ( | p | − | 9 20 | ) | − | 1250 | = | 4000 | − | 250 | p |
Left side of the equation = | 500 | p | − | 500 | × | 9 20 | − | 1250 |
= | 500 | p | − | 225 | − | 1250 |
= | 500 | p | − | 1475 |
500 | p | − | 1475 | = | 4000 | − | 250 | p |
500 | p | + | 250 | p | = | 4000 | + | 1475 |
750 | p | = | 4000 | + | 1475 |
750 | p | = | 5475 |
p | = | 5475 | ÷ | 750 |
= | 5475 | × | 1 750 |
= | 73 | × | 1 10 |
p | = | 73 10 |
p | = | 7.3 |
