Give the step-by-step reasoning process and then the final answer. A jewelry store is restocking its shelves. The necklace stand, which can hold 12 necklaces, currently holds 5 necklaces. The ring display, which can hold 30 rings, currently holds 18 rings. The bracelet display, which can hold 15 bracelets, currently holds 8 bracelets. The store's supplier charges $4 per necklace, $10 per ring, and $5 per bracelet. How much, in dollars, will the store need to pay to fill the displays?
The necklace stand needs another 12 5 = 7 necklaces. This will cost the store 7 * 4 = $28. The ring display needs another 30 18 = 12 rings. This will cost the store 12 * 10 = $120. The bracelet display needs another 15 8 = 7 bracelets. This will cost the store 7 * 5 = $35. In total, the store needs to pay 28 + 120 + 35 = $183.
The final answer: 183.
