I'm completely lost with this math problem: Nathan is buying decorations for his wedding reception. The reception hall will have 20 tables. Each table needs a linen tablecloth ($25 to rent), 4 place settings ($10 each to rent), and a centerpiece. Each centerpiece will have 10 roses ($5 each) and 15 lilies ($4 each). How much will the decorations cost?
Can you give me a hand?
