Mary had 6 lambs and 2 of the lambs had 2 babies each. She traded 3 lambs for one goat. One morning, she woke up and found an extra 7 lambs in the field. How many lambs does Mary have?
Thoughts? Step-by-step reasoning:
User
2 of her lambs had 2 babies each so that adds 2 * 2 = 4 lambs. She starts with 6 and adds 4 baby lambs so she had 6 + 4 = 10 lambs. She traded 3 of those lambs for a goat so she has 10 - 3 = 7 lambs. She has 7 and woke up to find 7 more lambs in the field so she has a total of 7 + 7 = 14 lambs.
Thus, the answer is 14.
