Question

Each morning, a veterinarian uses 24 3/4 gallons of water from Farrell to fill the animals' water bottles. Each afternoon, she adds 15.25 gallons of water to the barrel. How much has the column of water in the barrel changed after 5 days?

Answer 1

The column of water in the barrel decreases by 47.5 gallons after 5 days, based on daily usage of 24 3/4 gallons and an addition of 15.25 gallons each afternoon.

Step-by-step explanation:

The question asks for the total change in the column of water in a barrel over a period of 5 days, given that each morning 24 3/4 gallons are used and each afternoon 15.25 gallons are added. To solve this, we first need to find the total amount of water used and added each day, and then multiply that by the number of days.

Each morning, 24 3/4 gallons or 24.75 gallons of water are used, and in the afternoon, 15.25 gallons are added back. Therefore, the daily change in the barrel is the difference between these two amounts:

24.75 gallons (used) - 15.25 gallons (added) = 9.5 gallons (net change per day).

Multiplying the daily net change by the number of days gives us the total change over 5 days:

9.5 gallons/day x 5 days = 47.5 gallons.

The column of water in the barrel has decreased by 47.5 gallons after 5 days.
