Answer:
Lauren is on page 80 when Audrey is on page 80.
Explanation:
If Audrey reads 16 pages a day and she is on page 80, we can calculate how many days it took her to reach that page:
Number of days = Total pages read / Pages read per day
Number of days = 80 / 16
Number of days = 5 days
Now that we know Audrey took 5 days to reach page 80, we can assume that Lauren, who started reading the same day, would also be on the same page as Audrey since they began reading the novel together. Therefore, Lauren is also on page 80.
