A few years ago ,cement drivers were on stike for 46 days.Before the strike,these drivers earned $7.50 per hour and worked 260 eight -hour days a year.What percentage increase is needed in yearly income to make up for the lost time within 1 year
-----------------------------
Money lost during the strike:
(46)(8)(7.5) = $2760
----------------------------
Normal earnings for a year:
260*8(7.5) = $15,600
------------------------
Amount one driver needs to earn in the makeup year: 15600+2760 = 18,360
---------
Percentage increase:
2760/15600 = 0.1769 or 17.69%
