Question

Tammy purchased 20.5 centimeters of wire for $16.40.

Answer 1

$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:

$\implies \dfrac{16.40}{20.5}=\dfrac{164}{205}=\dfrac{41 \times 4}{41 \times 5}=\dfrac{4}{5}=0.8$

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