The formula for the common interest of a loan of a principal P with a simple interest yearly rate r (in decimal form) adter n days is
[tex]I = Pr × \frac{n}{360} [/tex]
Substituting the formula with the given data we get
[tex]1730 = P × 0.07 \times \frac{120}{360} [/tex]
[tex]1730 = P × 0.07 \times 0.3333[/tex]
[tex]1730 = P × 0.02333[/tex]
Dividing both sides by 0.02333:
[tex] \frac{1730}{0.02333} = P[/tex]
[tex]P = 74142.86[/tex]
Answer: P 74,142.86
