Final answer:
No, the bakery will not have enough time to bake all 7 batches of muffins before opening, as they would need approximately 4 hours and 40 minutes, which exceeds the available 4 hours.
Step-by-step explanation:
The question is whether a bakery has enough time to bake 7 batches of muffins before opening in 4 hours, given that each batch takes 2/3 of an hour to bake. To determine this, we calculate the total time needed to bake all batches by multiplying the number of batches by the time per batch:
- Time per batch = 2/3 hour
- Total time needed = 7 batches × (2/3 hour/batch)
- Total time needed = 14/3 hours or about 4 hours and 40 minutes
Since they have exactly 4 hours before opening and they need approximately 4 hours and 40 minutes, the bakery will not have enough time to bake all 7 batches of muffins. Therefore, the answer is B) No.
