To estimate the number of balls made per person each day, we divide the total number of tennis balls produced (139,968) by the number of workers (204):
139,968 / 204 ≈ 686.4
Therefore, each person on the production line is estimated to make approximately 686.4 tennis balls per day.
A factory produces 139968 tennis balls a day. There are 204 people working on the production line in the factory. Estimate the number of balls made per person each day.
