A. 229 ounces
B. 235 ounces
C. 259 ounces
D. 706 ounces
To calculate the amount of water Sarah will drink after the third week of increase, we need to find a 5% increase for each week.
1st week: 224 + 5% of 224 = 224 + 0.05*224 = 224 + 11.2 = 235.2 ounces
2nd week: 235.2 + 5% of 235.2 = 235.2 + 0.05*235.2 = 235.2 + 11.76 = 246.96 ounces
3rd week: 246.96 + 5% of 246.96 = 246.96 + 0.05*246.96 = 246.96 + 12.348 = 259.308
Rounded to the nearest ounce, Sarah will drink 259 ounces of water after the third week of increase.
Therefore, the answer is C. 259 ounces.
