Given that the baker has a total of 18 cups of flour, you know that the baker needs:
- This amount of flour for a batch of banana pancakes:
- This amount of flour for a batch of apple pancakes:
You know that the baker makes 8 batches of banana pancakes.
Let be "x" the greatest number of whole batches of apple pancakes that the baker can make.
You can set up this equation using the given data:
Now you need to solve for "x", in order to find its value:
Since the number of cups cannot be greater than 18 cups, you need to round down:
Hence, the answer is: Third option.
