Final answer:
To estimate the number of baseballs needed per season, assume an average of 10 baseballs used per game and add a buffer of 10% to the estimated number.
Step-by-step explanation:
To estimate the number of baseballs needed per season to compensate for the lost ones during games, we can use the average number of baseballs used in a game.
Let's assume that on average, 10 baseballs are used in each game. Since there are 81 home games in a season, the total number of baseballs needed would be 10 multiplied by 81, which is 810 baseballs.
However, it's always a good idea to have some extra baseballs, so we can add a buffer of 10% to the estimated number.
Therefore, the final estimate for the number of baseballs needed per season would be 810 + 10% of 810, which is 891 baseballs.
