To find the amount of water Sarah will drink after the third week of increase, we need to calculate her current amount of water and then increase it by 5% for three weeks.
First, let's find Sarah's current amount of water:
224 ounces
Next, let's calculate the increase for one week:
224 ounces * 5% = 11.2 ounces
Now, let's calculate her amount of water after the first week:
224 ounces + 11.2 ounces = 235.2 ounces
Now, let's calculate her amount of water after the second week:
235.2 ounces + 11.2 ounces = 246.4 ounces
Finally, let's calculate her amount of water after the third week:
246.4 ounces + 11.2 ounces = 257.6 ounces
Rounded to the nearest ounce, Sarah will drink 258 ounces after the third week of increase.
