1. Workers are compensated by firms with "benefits" in addi- tion to wages and salaries. The most prominent benefit of- fered by many firms is health insurance. Suppose that in 2000, workers at one steel plant were paid $20 per hour and in addition received health benefits at the rate of $4 per hour. Also suppose that by 2010 workers at that plant were paid $21 per hour but received $9 in health insurance ben- efits. LO17.1 a. By what percentage did total compensation (wages plus benefits) change at this plant from 2000 to 2010? What was the approximate average annual percentage change in total compensation? b. By what percentage did wages change at this plant from 2000 to 2010? What was the approximate average annual percentage change in wages? c. If workers value a dollar of health benefits as much as they value a dollar of wages, by what total percentage will they feel that their incomes have risen over this time period? What if they only consider wages when calculating their incomes? d. Is it possible for workers to feel as though their wages are stagnating even if total compensation is rising
