You have been asked to analyze the bids for 200 polished disks used in solar panels. These bids have been submitted by three suppliers: Thailand Polishing, India Shine, and Sacramento Glow. Thailand Polishing has submitted a bid of 2,000 baht. India Shine has submitted a bid of 2,000 rupees. Sacramento Glow has submitted a bid of $200. You check with your local bank and find that $1 = 10 baht and $1 = 8 rupees. Which company should you choose? If the final destination is New Delhi, India, and there is a 30% import tax, which firm should you then choose?
