What is the unitary method?

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

In Last year,

The Total income = $58,800

The Profit made by selling house =$27,940

The Monthly income by investment = $80

The Yearly income by investment = 12(80)  ( 1 year = $80)

= $960

Computation:

Also, 25 hours per week and 52 weeks per year as an hourly employee.

Let x be your hourly wages.

Then, yearly income by working = 25 x 52 x X

= 1300x

As per given,

1300x + 960 + 27,940 = 58,800

1300x = 29900

x = 23

In order to earn total income $59,970, we have

1300x + 960 + 27,940 = 59,970

x = 23.9

Difference = 23 -23.9= $ 0.90

Hence, You had to earn $0.90 more an hour last year in order to have a total income of $59,970.
