Paulita reads an average of 20 pages a day, and she has 6 days to read 10^2 pages. Let's rewrite this as an equality.
x×d>=p
x=20 d=6 p=10^2
20×6>=10^2
All that's left is to solve the inequality to see if it is true.
20×6>=10^2
20×6>=100
120>=100
Since 120 is greater than or equal to 100, this makes the statement true. Which, in turn, means Paulita will finish her reading.
