stock Float:ReturnSaleValue(Float:actual_price, Float:hours_bought, Float:hours_used, Float:quality, Float:rate_of_hours = 0.75, Float:rate_of_usage = 0.3)
{
    new Float:used = (((1.0 - (hours_used / hours_bought)) * rate_of_hours) - (hours_used / hours_bought));
    if (used < 0.0)
        used *= -1;
    
    new Float:deduct[2];
    deduct[0] = ((actual_price * ((used <= 0.0) ? (1.0) : (used))) * rate_of_usage);
    deduct[1] = (actual_price - (quality * (actual_price / 100.0)));

    return (actual_price - (deduct[0] + deduct[1]));

Lets calculate a simple GTX 970M:

Original Price: 455
Hours Bought: 8760 (1 year)
Hours Used: 1460 (2 months)
Current Quality: 70%

Код:

printf("GTX 970M would sale best at %f!", ReturnSaleValue(455, 8760, 1460, 70));

Output:
