What is unitary method?
The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
According to the given problem,
Cost for parts = $234
Total estimate = $509.00
Amount left from total estimate after spending for parts = $( 509 - 234 )
= $275
