<h3>What is unitary method?</h3>
The unitary method is a technique that involves determining the value of a single unit and then calculating the value of the requisite number of units based on that value. The term unitary refers to a single or unique entity. As a result, the goal of this approach is to determine values in reference to a single unit. The unitary technique is a method for determining the value of any necessary quantity by first obtaining the value of the unit (one) quantity.
Here,
$3 for 2.5 hours of work,
1 hour will cost $x,
3/2.5=x/1
2.5x=3
x=$1.2
Using the unitary technique, the unit rate for three dollars for two and a half hours of labour will be $1.2.
