问题 [br] Based on the graph shown, what was the average yearly decrease in the price of polyester between 1994 and 1998, inclusive?
选项 A、$1,250
B、$2,500
C、$3,750
D、$5,000
E、$6,250
答案 A
解析 The correct answer is A. To find the average yearly decrease, first find the total decrease over the 4 years. In 1994 the total price of polyester was approximately $35,000, and in 1998, it was approximately $30,000. So the difference is $5,000. Now, to find the average, divide by 4 years: 5,000 + 4 = 1,250.
