1. **State the problem:** We are given amounts of vinegar, water, and total cleaning solution in cups, and we want to understand the relationship between these quantities. 2. **Given data:** - Amount of vinegar = 3.5 cups - Amount of water = 3 cups (and 30 cups mentioned, likely a typo or separate data, we will consider 3 cups as water amount for the first problem) - Total amount of cleaning solution = 3.5 cups 3. **Formula and explanation:** The total amount of cleaning solution should be the sum of vinegar and water: $$\text{Total} = \text{Vinegar} + \text{Water}$$ 4. **Check the given values:** $$3.5 + 3 = 6.5$$ But the total given is 3.5 cups, which does not match the sum. 5. **Interpretation:** If the total is 3.5 cups, and vinegar is 3.5 cups, then water must be 0 cups for the equation to hold: $$3.5 + 0 = 3.5$$ 6. **Conclusion:** The data as given is inconsistent if water is 3 cups and total is 3.5 cups. If the water amount is 30 cups, then total would be: $$3.5 + 30 = 33.5$$ which is much larger than 3.5. Therefore, either the total amount or water amount is incorrect or the problem needs clarification. **Final answer:** The total amount of cleaning solution should equal the sum of vinegar and water, but the given numbers do not satisfy this relationship.
