The Smith family drinks 1 4/5 liters of apple juice each day. The apple juice is packed in 2-liter bottles. How many bottles does Mrs. Smith need to buy every week?
1.8 ^ 7 = 12.6 liters
It looks like Mrs. Smith should buy 7 bottles each week.
The following week she could buy 6 bottles.
Huh? I don't get it.
1.8 * 7 = 12.6 liters = 6 plus bottles

To find out how many bottles Mrs. Smith needs to buy every week, we first need to calculate the total amount of apple juice the Smith family drinks in a week.
Given that the Smith family drinks 1 4/5 liters of apple juice each day, we can calculate the weekly consumption as follows:
1 4/5 liters/day * 7 days/week = (7/5) liters/day * 7 = 49/5 liters/week = 9 4/5 liters/week.
Next, we need to determine how many 2-liter bottles are required to hold this amount of apple juice. We can divide the total weekly consumption by the capacity of each bottle:
(9 4/5 liters / 2 liters/bottle) ≈ 4.9 bottles.
Since we cannot have a fraction of a bottle, Mrs. Smith would need to buy at least 5 bottles every week to meet the demand for apple juice.
