A jewelry firm buys semiprecious stones to make bracelets and rings. The supplier quotes a price of $8.60 per stone for quantities of 600 stones or more, $9.00 per stone for orders of 400 to 599 stones, and $9.50 per stone for lesser quantities. The jewelry firm operates 105 days per year. Usage rate is 23 stones per day, and ordering costs are $43. a.
