To solve the problem, we first need to determine how many eggs Matthew used in total from the two dozen eggs he had.
- He has 2 dozen eggs, which is equal to \(2 \times 12 = 24\) eggs.
- He used 34 eggs from the first dozen and 56 eggs from the second dozen.
Adding the eggs he used:
- From the first dozen: 12 eggs (since a dozen is 12) and he used 34 from the total of 24 eggs. There's a mistake because he cannot use more eggs than he has. He actually used all 12 eggs from the first dozen.
- From the second dozen: 56 eggs.
So the calculation becomes:
- Used eggs from the first dozen: 12 (all of them)
- Used eggs from the second dozen: 56
Total eggs used: \[ 12 + 12 = 24 \text{ eggs} \]
But he only has 24 eggs total, and since he attempted to use 34 from the first dozen, we recognize he cannot. Thus:
- Maximum usable: \[ 12 + 12 = 24 \] So he used all of the eggs, which means there are 0 eggs left.
Since he used all the eggs, and to clarify the excess input:
- Total eggs left: \[ 0 \text{ eggs} \]
So to answer your question directly, Matthew has 0 eggs left after baking. None of the provided options correspond to this answer.
