Question

Diego pours 6.8 ounces of water from a full bottle. He estimates that he poured out 20% of the water in the bottle. About how much water was in the full bottle? Explain or show your reasoning. Diego pours out 25% of the remaining water. About how many ounces did he pour the second time? Explain or show your reasoning.

Answer 1

34 ounces

Explanation:

20% = 6.8

1% = 6.8*20

100% = 6.8 * 20/100 = 34 ounces

2nd solve:

after pouring 20%, the remaining water was = 34 - 6.8 = 27.2

2nd time pour = 27.2 * 25 / 100 = 6.8 ounces
