The day of the month that was 75% of the pond algae-free is: on day 28 or third day.
<h3>75% of the pond algae-free</h3>
Since we were told the algae doubled every day until it was covered in algae on day 30 of the month.
Hence:
Day 30 (First day)= It was 100% covered.
Day 29 (Second day)=It was 50% covered.
