This increased the that the remaining students had to pay by 12.50 php per student. How many students actually contributed to the gift?

Let the number of people be $x$
$$\text{Number of People}*Pay=Total$$$$x*12.50=500$$$$12.5x=500$$Divide both sides by $12.5$
$$\frac{12.5x}{12.5}=\frac{500}{12.5}$$Cross the $12.5$ on the LHS
$$\frac{\cancel{12.5}x}{\cancel{12.5}}=\frac{500}{12.5}$$
$$x=\frac{500}{12.5}$$
Solve for that to find the number of children who payed
