Questions: Cal fomere Ba (s) 12 per hour 15 per hour 27 per hour 39 per hour

Solution Steps

The graph shows the relationship between hours used and cost. We are given two points on the graph: (1, 27) and (2, 42). This means that when 1 hour is used, the cost is $27, and when 2 hours are used, the cost is $42.

The difference in cost between 2 hours and 1 hour is \(42 - 27 = 15\). The difference in hours is \(2 - 1 = 1\).

The cost per hour is the difference in cost divided by the difference in hours: \(\frac{15}{1} = 15\).
