Answer:

40.42 ounces.

Explanation:

Initial volume of water: 58 ounces

"A group of blue jays came by and drank 3.18 ounces", it means that they substracted 3.18 ounces, therefore we do the following:

58 ounces - 3.18 ounces= 54.82 ounces.

After that, "...a vulture swooped in and drank fourteen and two fifths ounces of the water", this means that 14 ounces + 2/5 ounces were substracted from the bath.

As for right now, there are 54.82 ounces, let's calculate how much there was after the vulture passed by:

54.82 ounces - 14 ounces= 40.82 ounces.

40.82 ounces - 2/5 ounces, let's convert the fraction to a decimal and substract:

40.82 ounces - 0.4 ounces= 40.42 ounces.

Therefore, the final volume of water remaining in the bath is 40.42 ounces.

This problem could be solved by adding up all the substractions and substracting the total amount from the initial volume of water in the bath. This would be the operation:

58 - (3.18 + 14 + 2/5)=

58 - (3.18 + 14 + 0.4)=

58 - (17.58)=

40.42 ounces.
