Answer: B, about 280 ounces
16.9 + 15.2 = 32.1
32.1 * 7 = 224.7
Not A because she doesn't drink 30 oz she drinks 32.
B is the closest and is rounding both numbers up.
C is false because you don't multiply by 10, you multiply by 7 because of the 7 days in a week.
D is false for the same reason as C.
