She designed three wind turbines and built a model of each one. She used the models to 7 estimate the efficiency of each wind turbine. The efficiency is the percentage of the wind's energy that can be converted into electrical energy by the turbine. She also estimated how Time much it would cost to manufacture each wind turbine. Her results are shown below. elapsed 08 40 Design Efficiency of the turbine Cost to manufacture the turbine HR MIN SEC A 51% $490,000 Challenge B 46% $450,000 Stage 2 of 2 C 44% $520,000 Get 4 of 5 correct If Hannah chose design B, which statement would explain her choice? O Her goal was to manufacture a wind turbine for less than $500,000 with an efficiency of at least 50%. Her goal was to manufacture the least expensive wind turbine with an efficiency of more than 45%. Submit Work it out Not feeling ready yet?
