Answer: KWD; $99474 avoided
Step-by-step explanation:
From the question, we're informed that the buyer was aware that the KWD had strengthened against the USD since 2003 coupled with the fact that KWD is a floating currency, it'll have been better if the contract was written in KWD as this will mean lesser money is paid.
Since 1 USD = 0.2816 KWD, and has been predicted to reduce to 1 USD = 0.265, the company would save:
= $1,588,000 × (0.2816-0.265)/0.265
= ($1,588,000 × 0.0166)/0.265
= $26360.8/0.265
= $ 99474
