hannah needed to decide which type of wind turbine to manufacture for a wind farm. she designed three wind turbines and built a model of each one. she used the models to estimate the efficiency of each wind turbine. the efficiency is the percentage of the winds energy that can be converted into electrical energy by the turbine. she also estimated how much it would cost to manufacture each wind turbine. her results are shown below.\n| design | efficiency of the turbine | cost to manufacture the turbine |\n| ---- | ---- | ---- |\n| a | 51% | $490,000 |\n| b | 46% | $450,000 |\n| c | 44% | $520,000 |\nif hannah chose design b, which statement would explain her choice?\nher goal was to manufacture a wind turbine for less than $500,000 with an efficiency of at least 50%.\nher goal was to manufacture the least expensive wind turbine with an efficiency of more than 45%.

Answer

Brief Explanations:

Design B has an efficiency of 46% (more than 45%) and a cost of $450,000 which is less expensive compared to other designs with relatively high - efficiency. The first statement's efficiency requirement (at least 50%) is not met by design B.

Answer:

Her goal was to manufacture the least expensive wind turbine with an efficiency of more than 45%.
