Answer :
Final answer:
Eden adds together the amounts of olive oil and vinegar needed for one batch of salad dressing (1.5 cups of olive oil and 0.75 cups of vinegar = 2.25 cups). Eden then multiplies this amount by the number of batches she makes (3.5 batches * 2.25 cups/batch = 7.875 cups) to find the total amount of salad dressing Eden makes.
Explanation:
To solve this problem, we will sum up the amount of olive oil and vinegar for one batch of the salad dressing and then multiply it by the number of batches that Eden makes. For one batch, 1.5 cups of olive oil and 0.75 cups of vinegar are used, totaling to 1.5 + 0.75 = 2.25 cups of salad dressing for one batch. Eden makes 3 1/2 batches, which can be rewritten as 3.5 batches, so multiply the cups per batch by the number of batches: 2.25 cups x 3.5 = 7.875 cups. Therefore, Eden makes 7.875 cups of salad dressing.
