Question

a utility company says that the cost of operating a hair dryer is \\(\frac{1}{7}\\)¢ per minute. find the cost of operating the hair dryer for 14 minutes. the cost of operating the hair dryer is \\(square\\)¢. (type a whole number or a simplified fraction.)

Explanation:

Step1: Identify the rate and time

The cost per minute is $\frac{1}{7}$ ¢, and the time is 14 minutes. To find the total cost, we multiply the cost per minute by the number of minutes.
So the formula is: Total Cost = Cost per minute × Time, which is $\frac{1}{7} \times 14$.

Step2: Perform the multiplication

Simplify $\frac{1}{7} \times 14$. We can rewrite 14 as $\frac{14}{1}$, then multiply the numerators and denominators: $\frac{1 \times 14}{7 \times 1} = \frac{14}{7}$.
Simplify $\frac{14}{7}$ to get 2.

Answer:

2
