Calculation of Water Usage

To determine if the water in the barrel will last for a week and how much water will be left, we need to calculate the total amount of water used each day and subtract it from the initial amount of water in the barrel.

Given: - Initial amount of water in the barrel: 65 liters - Water taken in the morning: 3 liters - Water taken in the evening: 6 liters

Calculation:

To calculate the total amount of water used each day, we add the water taken in the morning and the water taken in the evening: - Total water used per day = 3 liters + 6 liters = 9 liters

To calculate the total amount of water used in a week, we multiply the total water used per day by the number of days in a week: - Total water used in a week = 9 liters/day * 7 days/week = 63 liters

To calculate the amount of water left in the barrel after a week, we subtract the total water used in a week from the initial amount of water in the barrel: - Water left in the barrel = Initial amount of water - Total water used in a week - Water left in the barrel = 65 liters - 63 liters = 2 liters

Answer:

Based on the given information, the water in the barrel will last for a week, and there will be 2 liters of water left in the barrel at the end of the week.
