A 9-foot roll of red ribbon costs $0.42. What is the unit price, rounded to the nearest cent?

Answer 1

To find the unit price of the red ribbon, you need to divide the total cost by the length of the ribbon in feet.

The total cost of the ribbon is $0.42, and the length of the ribbon is 9 feet.

Now, calculate the unit price:

\[ \text{Unit Price} = \frac{\text{Total Cost}}{\text{Length}} = \frac{0.42}{9} \approx 0.04666666... \]

Now, rounding this to the nearest cent:

\[ 0.04666666... \approx 0.05 \]

Therefore, the unit price of the ribbon is $0.05 per foot.
