Joe Higgins is thinking about how much time to spend studying for a biology exam tomorrow. Using "utility units" he measures the benefits and costs of study; his calculations are shown in the following table. Hours spent studying 0 3 4 5 6 Total benefit 100 180 240 280 300 300 Total cost 50 100 150 200 250 300 Net benefit a. Fill in the fourth row for net benefit in the table.
