Answer 1

your right 30 × 7 = 210 is the right answer

Explanation:

Answer 2

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.
