Answer 2

Problem 1: Let's calculate the number of days in the pool.

Given: - Initially, there were 20 days. - 8 days were spent. - 5 days were added.

To find the total number of days, we can use the following equation: Total days = Initial days - Days spent + Days added

Substituting the given values: Total days = 20 - 8 + 5

Solution: Total days = 17

Problem 2: Let's calculate the number of days in the pool.

Given: - Initially, there were 20 days. - 8 days were spent. - The current number of days is 17.

To find the number of days added, we can use the following equation: Days added = Initial days - Days spent - Current days

Substituting the given values: Days added = 20 - 8 - 17

Solution: Days added = -5

Therefore, the number of days added is -5.

Please note that it is not possible to have a negative number of days added. It seems there might be an error in the given information.

Problem 3: Let's calculate the number of days in the pool.

Given: - Initially, there were 17 days. - 8 days were spent. - 5 days were added.

To find the total number of days, we can use the following equation: Total days = Initial days - Days spent + Days added

Substituting the given values: Total days = 17 - 8 + 5

Solution: Total days = 14

Therefore, the total number of days in the pool is 14.
