PROBLEM: 3 cups water wasted in 24 hours (1 day)

FIND: How many cups are wasted in a week (7 days)?

SOLUTION 1: You can add 3 for each day of the week so 3+3+3+3+3+3+3 = 21 Cups

SOLUTION 2: Since we are using the same number for each day, we can multiply 3*7 = 21 Cups

Either solution will get you the answer you need but the purpose of this question if to go with Solution 2 which would be faster when the problem becomes more complex.
