A caterer for a wedding reception wants to use a recipe for eggplant salad that recommends using 1.8 kg of eggplant for 10
guests. However, in her area, eggplant is only sold by the pound. If 180 guests are expected, how many pounds of eggplant should the caterer purchase?
180 guests / 10 guests/recipe = 18 recipes
18 recipes x 1.8 kg/recipe = 32.4 kg
32.4 kg x 2.2 lb/kg = 71.28 pounds of eggplant
