At a factory, two machines pack bottles into boxes for shipping. Machine A can pack 8 boxes per minute, and Machine B can pack 11 boxes per minute. Before shipment, an inspector found that 7 of
the boxes packed by Machine A were defective and could not be shipped. At least 200 boxes packed
by Machine A were approved for shipment. Write and solve an inequality to find the amount of time
Machine A spent packing the boxes that were approved for shipment.
