Answer:
$0.80
Step-by-step explanation:
Given:
- 20.5 cm wire costs $16.40.
To find the unit price in dollars per centimeter, divide the total amount by the number of centimeters:
[tex]\implies \dfrac{16.40}{20.5}=\dfrac{164}{205}=\dfrac{41 \times 4}{41 \times 5}=\dfrac{4}{5}=0.8[/tex]
Therefore, the unit price in dollars per centimeter is $0.80.
