The best thing to do is to find out what 1/5 is equal to, and you can do this by dividing $13.32 by 3
13.32/3= 4.44
Therefore, 1/5 = $4.44
As you're looking for the total amount, you multiply this by 5.
$4.44*5= $22.20
Therefore, the present cost $22.20

Answer:
25 to the power of 3.
Step-by-step explanation:
we got 25 schools ordering newspapers for 25 classes of 25 kids. that's 25x25x25. it wants the number of pages total, and since there's 25 pages in each newspaper we add another 25. so it's 25x25x25x25, also known as 25 to the power of 3.
