The number of new ants appearing in Mark's bedroom each day can be found to be 12 ants per day
<h3>How to find the number of ants?</h3>
To find the number of new ants coming into Mark's room every day, you should divide the difference between the number of ants on consecutive days by the difference between the days since Mark moved in.
The difference between the number of ants from day 3 to 5 is:
= 90 - 66
= 24 ants
The difference in the number of days:
= 5 - 3
= 2 days
The number of new ants is therefore:
= 24 / 2
= 12 ants
