[Question]: A zoo has 16 pandas, paired into mates (in the same zoo). Only 25% of the panda couples get pregnant after mating. If they each have one baby, how many panda babies are born?
[Answer]: First divide the number of pandas by 2 to find the number of couples: 16 pandas / 2 = 8 panda couples. Then multiply that number by 25% to find the number of babies: 8 panda couples * 25% = 2 panda babies.
So the answer is 2.

[Question]: Lisa has 18 more dresses than Ana. If the number of their dresses combined is 48, how many dresses does Ana have?
[Answer]: If Lisa's surplus of 18 dresses is taken away from the total, they will have 48 - 18 = 30 dresses in total. They would each have the same number of dresses from these 30 i.e. 30 / 2 = 15 dresses which is the number of dresses that Ana actually has.
So the answer is 15.

[Question]: Bailey bought 8 dog treats and an additional 2 chew toys. She also got 10 more rawhide bones. Sadly, she forgot her money and had to split the charges equally across 4 credit cards. How many items were included in each charge?
[Answer]:
Bailey got 8 + 2 = 10 dog supplies. After adding the rawhide bones, she had 10 + 10 = 20 dog supplies. She needed to split the charges across 4 cards, so each charge had 20 * .25 = 5 items.
So the answer is 5.
