question 16

Explanation:

Step1: Find the cost per minute

The cost per minute \(c\) is calculated by dividing the total cost by the number of minutes. Given that the cost is \(\$50\) for \(170\) minutes, so \(c=\frac{50}{170}\) dollars per minute.

Step2: Calculate the cost for \(1504\) minutes

Let \(x\) be the cost for \(1504\) minutes. Since the cost is proportional (cost per minute is constant), we use the formula \(x = c\times1504\). Substitute \(c = \frac{50}{170}\) into the formula: \(x=\frac{50}{170}\times1504\).
