A bakery needs to make 7 batches of muffins before opening in 4 hours. Each batch of muffins takes 2/3 hour to bake.

To find 2/3 of an hour you need to spilt the hour up so you’d say each third is 20 minutes therefore, each batch of muffins takes 40 minutes, so 40*7 you get 280 and divided by 60 it’s 4.6. I don’t know what the question is exactly asking for but they will be a little bit behind schedule with their muffins

4should be the last one n=4
