whether the given statement is true or false.
Answer to Problem 13PPS
The givenstatement is false
Explanation of Solution
Given: Use the graph at the right to determine whether each statement is true or false.
the total cost varies directly with the number of rooms.
Calculation:
Consider three points from the graph that shows relationship between total cost and number of rooms (1,110), (1,5,120) and (2,140)
The total cost varies directly with number of rooms only when ratio of two variable quantities is constant and the graph of direct variation passes through the origin.
Since, the graph does not pass through the origin.
Conclusion:Therefore,thegiven statement is false
