Grace is looking to plant some lettuce in her raised bed garden. Her raised bed is comprised of 2 large beds on top with 2 medium beds on the bottom. The top bed can hold 4 rows of lettuce with 25 seeds being sown per row. The medium bed can house 3 rows with 20 seeds being sown per row. How many seeds can Grace plant in all four beds of her raised bed garden? Let's think first. Chain of thought:

A large bed can hold 4 rows with 25 seeds per row, 4 * 25 = 100 seeds per large bed. 100 seeds per large bed and there are 2 beds, 100 * 2 = 200 seeds needed in total for both large beds. A medium bed can hold 3 rows with 20 seeds sown per row, 3 * 20 = 60 seeds per medium bed. 60 seeds per medium bed and there are 2 medium beds, 60 * 2 = 120 seeds needed in total for both medium beds. 200 seeds needed for the large beds combined with 120 seeds needed for the medium beds comes to 200 + 120 = 320 seeds needed to plant all four beds of the raised garden bed.
Therefore, the answer is 320.
