Question

Tammy purchased 20.5 centimeters of wire for $16.40.

Find the unit price in dollars per centimeter.
If necessary, round your answer to the nearest cent.

Answer 1

Answer:
Each cm of wire is $0.80

Step-by-step explanation:
16.4/20.5=0.8

Answer 2

$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.
