mulative Review 3 tion A Multiple-Choice Questions 4 file costs 5 k dollars and a notebook costs \( \frac{1}{6} \) of the file. Which expression shows the cost of the notebook in dollars?

To find the cost of the notebook in dollars, we need to use the information given in the problem. 1. The cost of the file is \( 5k \) dollars. 2. The cost of the notebook is \( \frac{1}{6} \) of the cost of the file. Now, we can express the cost of the notebook using the cost of the file: \[ \text{Cost of notebook} = \frac{1}{6} \times \text{Cost of file} \] Substituting the cost of the file: \[ \text{Cost of notebook} = \frac{1}{6} \times 5k \] Now, we can simplify this expression: \[ \text{Cost of notebook} = \frac{5k}{6} \] Thus, the expression that shows the cost of the notebook in dollars is: \[ \frac{5k}{6} \]
