Answer:
6
Step-by-step explanation:
We know it would reproduce every once hour because of the statement, "One type of bacteria reproduces once every 60 minutes.". We would do 4(1) because there are 4 hours and it reproduces once every hour. 4(1) is 4. Then we would add 4+2 because there were 2 cell there to begin with. 4+2=6.
