A man will pay RM 46000 to renovate an office . If the construction materials cost 25% more and the labour costs 30% more , he will need to pay RM 58540. Find the original cost of the construction meterial and the cost of labour .(Used equation)

Answer 1

The cost of renovating the office consists of construction materials and labour costs.
So we let x and y be cost of construction materials and labour respectively.
This means x + y = 46000

If the materials are 25% more and labour 30% more, renovation costs are RM58540.
So our second equation is
125/100x + 130/100y = 58540

Now we have 2 equations so we can solve for both unknowns. :)
