Question 15.   Use the graph paper to answer this question.
A tourist boat operator provide x trips to Island A and y trips to Island B per day. The service provided is based on the following constraints:

I)       The total number of trips provided is not more than 16.
II)     The number of trips to Island A is not more than three times the number of trips to Island B.
III)   The fare per trip to Island A is RM60 and the fare per trip to Island B is RM30. The total fare collection per day is not less than RM540.
(a) Write three inequalities, which satisfy all the above constraints.
(b) Using a scale of 2 cm to 2 trips on both axis, construct and shade the region R which satisfies all of the above constraints.
(c) Using the graph constructed in 15(b), find
(i) the minimum number of trips to Island B if 8 trips to Island A are provided per day,
(ii) the maximum total profit per day if the profit per trip to Island A is RM40 and the profit per trip to Island B is RM20.
