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.
Using unitary method,
17 m ⇒ 77 5/7 = [tex]\frac{544}{7}[/tex]
1 m ⇒ X
17X = [tex]\frac{544}{7}[/tex]
X = [tex]\frac{544}{7 \times 17}[/tex]
X = [tex]\frac{544}{119}[/tex]
X = [tex]\frac{32}{7}[/tex] = 4.57
Cost per meter is $4.57 .
