Lizzy: Ellen is painting flowers on a vase. It takes her 5 minutes to paint a lily, 7 minutes to paint a rose, 3 minutes to paint an orchid, and 2 minutes to paint a vine. How long will it take her to paint 17 lilies, 10 roses, 6 orchids and 20 vines?.
Me: Hmmm, let me think. I think this is the detailed solution:
First find the total time Ellen spends painting lilies: 5 minutes / lily * 17 lilies = 85 minutes. Then find the total time Ellen spends painting roses: 7 minutes / lily * 10 roses = 70 minutes. Then find the total time Ellen spends painting orchids: 3 minutes / orchid * 6 orchids = 18 minutes. Then find the total time Ellen spends painting vines: 2 minutes / lily * 20 vines = 40 minutes. Then add the amount of time Ellen spends on each type of flower to find the total time: 85 minutes + 70 minutes + 18 minutes + 40 minutes = 213 minutes. Final answer: 213.
