Final answer:
To find out how many pounds of raw material need to be purchased in April, calculate the raw materials needed for April's production and the raw materials inventory needed for May's production.
Step-by-step explanation:
To determine how many pounds of raw material need to be purchased in April, we need to calculate the raw materials needed for April's production and the raw materials inventory needed for May's production. Let's start with April: April's production is 43,000 units and each unit requires 4 pounds of raw materials, so the total raw materials needed for April's production is 43,000 units * 4 pounds/unit = 172,000 pounds. The raw materials inventory needed for May's production is 25% of May's production needs, which is 25% * 44,000 units * 4 pounds/unit = 44,000 pounds. Therefore, the total pounds of raw material that need to be purchased in April is 172,000 pounds + 44,000 pounds = 216,000 pounds.
