+600 Martin works for 69 hours every week. He is paid R450 per hour.
a) How much does he earn every month of January.
69 hours = 1 week
= 7 days
69/7 = 9.8 hours
9.8*31 = 303.8 hours
303.8*450 = R136,710
b) If he pays 10% in tax and spends 1/5 on food every month. How much is he left with in January.
136,710*10/100 = 13,671
136,710-13,671 = 123,039
123,039*1/5 = 24,607.8
123,039-24,607.8 = R98,431.2
c) Write down the ratio of tax paid to food in it's lowest term.
Tax : Food
13,671 : 24,607.8
5 : 9
Am I correct?
+118673 Hi Eloise,
These questions are really awful because they can be interpreted in different ways.
Your interpretation of the first one sound ok. Although, there is no reason to think that he does work 7 days a week. Mind you, he is working VERY long hours. Also 69/7=9.857.... which is closer to 9.9 then it is to your 9.8hours.
The second one is also very badly worded. We do not know if it is 1/5 before the tax is taken out of afterwards.
But again, your interpretation is reasonable and the maths you have done appears to be corrrect:)
The last one looks reasonable too :))
