Zama Zondi is employed in the manufacturing section of a factory. She is entitled to three weeks' paid leave per annum and a bonus equal to three weeks' normal wage. She is also entitled to 10 paid public holidays per year. A normal day is 9 hours, which include 90 minutes for tea and lunch breaks; and a normal week is 5 days Monday to Friday. Normal wage per hour is R110 for Zama. The company contributes 12% of normal wages on behalf of employees towards the pension fund. Normal idle time is considered as 5% of available hours. What is Zamas labour cost that the factory will use for budgeting purposes?

I see a lot of people say that the answer is R257 400 but why wasn't the Bonus and Pension taken into account ?
