He then went to see the oranges being harvested. He found out that they harvest 703 sacks per day and discard 732 of them. How many sacks of oranges will they have after 692 days of harvest?
1. On the first day, they harvest 703 sacks and discard 732. 
2. On the second day, they harvest 703 more sacks and discard 732 more. 
3. On the third day, they harvest 703 more sacks and discard 732 more. 

This continues until they've completed 692 days of harvest. 

At the end of 692 days, they will have harvested 692 * 703 = 486,876 sacks of oranges, and discarded 692 * 732 = 492,224 sacks of oranges.
