Laticia knitted 4 pairs of socks for her nephew. She did such a good job that everyone asked her to start selling them. In the first week, she knitted 12 pairs of socks. In the second week, she knitted 4 more pairs than the week before. On the third week, she only knitted half of the total of the first two weeks. In the fourth week, she knitted 3 fewer pairs than the week before. How many pairs of socks did Laticia knit altogether?
Thoughts? Step-by-step reasoning:
In the second week, she knitted 12 + 4 = 16 pairs of socks. In the first two weeks, she knitted 12 + 16 = 28 pairs of socks. On the third week, she knitted 28 / 2 = 14 pairs of socks. On the fourth week, she knitted 14 - 3 = 11 pairs of socks. Altogether, Laticia knitted 4 + 12 + 16 + 14 + 11 = 57 pairs of socks.
Thus, the answer is 57.
