Libby is building an igloo in her backyard using bricks of snow. She builds her igloo in rows, using a total of 10 rows of bricks of snow. The bottom half of the igloo has 12 bricks of snow in each row while the top half of the igloo has 8 bricks of snow in each row. How many bricks of snow did Libby use for her igloo? Give me reasons, before answering the question

In the bottom half of the igloo, there are 10 rows / 2 = 5 rows of bricks of snow. So in the bottom half of the igloo, there are 5 rows * 12 bricks of snow in each row = 60 bricks of snow. In the top half of the igloo, there are 5 rows * 8 bricks of snow in each row = 40 bricks of snow. There is therefore a total of 60 + 40 = 100 bricks of snow in the igloo. So the final answer is 100.
