From Monday to Thursday, the cobbler works for 8 hours each day, so the total number of hours worked is 8 hours/day x 4 days = 32 hours.
If the cobbler can mend 3 pairs of shoes in an hour, then in 32 hours, the cobbler can mend 32 hours x 3 pairs/hour = 96 pairs of shoes.
On Friday, the cobbler only works from 8am to 11am, which is a total of 3 hours.
In these 3 hours, the cobbler can mend 3 hours x 3 pairs/hour = 9 pairs of shoes.
Therefore, in a week, the cobbler can mend a total of 96 + 9 = 105 pairs of shoes.
