Which is the best estimate for the number of minutes on the calling card advertised below?
$\begin{array}{l} A) 10 \min \\ B) 20 \min \\ C) 50 \min \\ D) 200 \min \end{array}$

Short Answer

Expert verified

The correct option is $D) 200 \min$ .

Step by step solution

Step 1. Determine the total amount and rate.

The total amount is $10 and rate is $5.4$ cents per minute.

Step 2. Write the equation.

Let the maximum number of minutes is represented by x.

The given expression can be written as:

$x = \frac{10 (100)}{5.4}$

Step 3. Solve for x.

$\begin{array}{l} x = \frac{1000}{5.4} \\ x = 185.185 \end{array}$

Hence, the maximum number of minutes can be $185.185$

Therefore, the correct option is $D) 200 \min$ .
