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? Give me reasons, before answering the question
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 final answer is 5.
