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:


\implies (16.40)/(20.5)=(164)/(205)=(41 * 4)/(41 * 5)=(4)/(5)=0.8

Therefore, the unit price in dollars per centimeter is $0.80.
