Key Information: stock performance graph the following graph compares the most recent five-year performance of the company 2019s common stock with ( 1 ) the standard & poor 2019s 500 ae index and ( 2 ) the standard & poor 2019s 500 ae materials index , a group of 25 companies categorized by standard & poor 2019s as active in the 201cmaterials 201d market sector .
Reasoning Steps:
Step: minus2-1(177.79, 100) = 77.79
Step: divide2-2(const_1, const_5) = 0.2
Step: minus2-3(#1, const_1) = -0.8
Step: exp2-4(#0, #2) = 1.2225
Step: minus2-5(#3, const_1) = 22.25%
Program:
subtract(177.79, 100), divide(const_1, const_5), subtract(#1, const_1), exp(#0, #2), subtract(#3, const_1)
Program (Nested):
subtract(exp(subtract(177.79, 100), subtract(divide(const_1, const_5), const_1)), const_1)
