Tiffany & Co. often suggests to her male customers who buy engagement rings that they also purchase a necklace as a wedding gift for their bride. As a courtesy to men purchasing the engagement rings, she discounts amethyst strands 18 and shorter by 35% and amethyst strands longer than 18 by 45%. The rings have a 100% mark-up on cost and the necklaces have a 60% mark-up on cost. If a customer purchases both the ring for RM376 and the 22 amethyst strand for RM668, what would be the total purchase price? How much did the customer save by purchasing the ring and necklace together?
