Answer:
D. 25,000
Step-by-step explanation:
Initially, with an investment of $8,000, the business was able to produce 10,000 units of products.
Changes were made and productivity increased by 25%.
25% of 10,000 = 25/100 x 10,000 = 2,500 units
Which means with an investment of $8,000, 12,500 units of products can now be produced.
Now, the business doubled its investment. This means that the units of products produced will also doubled:
12,500 x 2 = 25,000 units.
Hence, the correct option is D.
