What is the unitary method?

A unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.

On Monday, it took 5 builders 3 and a 1/2 hours to build a wall.

An identical wall needs to be built on Tuesday but only 2 builders are available.

Each builder is paid £9.30 for each hour or part of an hour they work.

The first step is to find the number of hours it takes for 5 builders;

The time is taken by 1 bulider;

[tex]\rm = 3\dfrac{1}{2}\times 5\\\\=\dfrac{3\times 2+1}{2}\times 5\\\\ =\dfrac{6+1}{2}\times 5\\\\ = \dfrac{7}{2}\times 5\\\\ = 3.5 \times 5\\\\= 17.5[/tex]

The time for 2 builders is given by;

1 builder = 17.5 hours

2 builders = 17.5 ÷ 2 = 8.75 hours

Each builder is paid £9.30 for each or part hour they work so

9.30 hourly pay rate × 9 hours work of work = £83.70

Hence, Each worker will be paid £83.7.
