Answer:
There are 11.25 cups of salad dressing
Explanation:
A different salad dressing uses a combined total of 2.5 cup of olive oil and vinegar per batch.
Hence:
1 batch = 2.5 cup of salad dressing
4.5 batches = x
Cross Multiply
1 × x = 4.5 × 2.5
x = 11.25 cups of salad dressing.
Is 8 cups in 4 1/2 batches a reasonable answer? No it is not.

4.5 = 1 decimal place
2.5 = 1 decimal place
Adding the decimal places together = 2 decimal places.
