The following table provides entropy about how many a(prenominal) plastic chairs can be produced per hour.Assume that apart from labor there are additional labor cost of $2 per chair. How many workers will be hired if the hourly wage for workers is $70? A of Workers Chairs Produced Income Prod. Cost Wage Net Income 1 10 120 20 70 30 2 18 216 36 140 40 3 24 288 48 210 30 4 28 336 56 280 0 5 30 360 60 350 -50 There will be hired only 2 workers, because after one hour of production and paying for the work, with 2 workers the company will have the highest net income fitted to $40.

A Year CPI Nominal Salary Real Salary 1990 1. 30 $x $(y+2%) 2000 1. 69 $35 $y Y=35/1. 69=20. 71 (Real Salary for 2000) Y+2%= 20. 71 + 20. 71*0. 02=21. 1242 (Real Salary for 1990) X= 21. 1242*1. 30=27. 4614 (Nominal Salary for 1990) Problem 5 Q A labor contract provides for a first-year wage of $10 per hour, and specifies that the real wage will rise by 3 per centum in the present moment year of the contract and by another 3 percent in the third year.The CPI is 1. 00 in the first year, 1. 07 in the second year, and 1. 15 in the third year. What dollar wage must be paid in the third year? A Year CPI Nominal Salary Real Salary 1 1. 00 10 Y1=10 2 1. 07 X1 Y2=(Y1+3%) 3 1. 15 X2 Y3=(Y2+3%) Y2 = 10+10*0. 03 = 10. 3 (Real Salary Second Year) Y3 = 10. 3 + 10. 3*0. 03 = 10. 609 (Real Salary terzetto Year) X1 = 10. 3*1. 07 = 11. 021 (Nominal Salary Second Year) X2 = 10. 609*1. 15 = 12. 20 (Nominal Salary triad Year)
