Assembling machine A packs chocolate boxes at a rate of 270 packets per hour, while assembling machine B packs identical chocolate boxes at a rate of 360 packets per hour. In a day, machine A works for \(x\) hours, machine B works for \(y\) hours, and together they pack a total of 3,600 boxes. Which equation represents this situation?
A\(270x + 360y = 3,600\)
B\(\frac{1}{270}x + \frac{1}{360}y = 3,600\)
C\(630(x + y) = 3,600\)
D\(\frac{x + y}{630} = 3,600\)
