Patrick buys 16 oz. of pancake batter to make breakfast. He uses about 2.75 oz. of batter per pancake. If he used 13.15 oz. of batter so far, is it reasonable to think that he has enough batter left for another pancake of the same size?
To determine if Patrick has enough batter left for another pancake, we need to subtract the amount of batter he has used from the amount of batter he bought:
16 oz. - 13.15 oz. = 2.85 oz.
Since Patrick has 2.85 oz. of batter left, which is more than the required 2.75 oz. per pancake, it is reasonable to think that he has enough batter left for another pancake.
