Looking at the table, we see that the total product for the fifth worker is not given. However, we can calculate it by finding the difference between the total product of the fourth worker and the total product of the third worker. Thus, the total product by the fifth worker is:

Total product by fifth worker = Total product by fourth worker - Total product by third worker 
= 370 - 285 
= 85

Therefore, the total product by the fifth worker is 85 units. The best choice is E.
