An online retailer wants to expand its product offerings by adding 1,000 new items to its inventory. Each item has an average wholesale cost of $25 and will require $5 in packaging materials. The company plans to store these items in a rented warehouse space that costs $0.10 per square foot per month. If each item occupies 2 square feet of space, calculate the monthly rent for the warehouse and the initial investment required to add these new products to their inventory.

First, we need to determine the total square footage required for storing the 1,000 new items. Since each item occupies 2 square feet of space, this means that the company needs 1,000 * 2 = <<1000*2=2000>>2,000 square feet of warehouse space.

Next, we calculate the monthly rent for the warehouse by multiplying the cost per square foot ($0.10) by the total square footage (2,000). This gives us a monthly rent of $0.10 * 2,000 = $<<0.10*2000=200>>200.

Now, let's calculate the initial investment required to add these new products to their inventory. The average wholesale cost of each item is $25 and there are 1,000 items, so the total wholesale cost is $25 * 1,000 = $<<25*1000=25000>>25,000. Additionally, each item requires $5 in packaging materials, which amounts to $5 * 1,000 = $<<5*1000=5000>>5,000.

Therefore, the initial investment required to add these new products to their inventory is $25,000 (wholesale cost) + $5,000 (packaging materials) = $<<25000+5000=30000>>30,000.
