 
 <translate> Through March, Dr. Banks gave out 53 + 67 + 46 = 166 toothbrushes. Before giving away toothbrushes in April, he had 330 - 166 = 164 toothbrushes remaining. Between April and May, he gave out the remaining 164 / 2 = 82 toothbrushes each month. Dr. Banks gave 82 toothbrushes in his busiest month and 46 toothbrushes during the slowest month. The difference would be 82 - 46 = 36 more toothbrushes in the busiest month.
