The total number of apples delivered was: 180 apples x 12 crates = <<180*12=2160>>2160 apples

So, the number of remaining apples after throwing away the rotten ones was: 2160 apples – 160 apples = <<2160-160=2000>>2000 apples

And now, we can find the total number of boxes of apples by dividing the remaining number of apples by the number of apples per box: 2000 apples / 20 apples/box = <<2000/20=100>>100 boxes of apples.
