of type A and y pillows of type B. The time taken to produce a pillow of type A is 20 minutes
and a pillow of type B is 30 minutes.
The production of the pillow per day is based on the following constraints.
I. : The time taken to make pillows of type A is not more than the time taken to make
pillows of type B.
II. : The total number of pillows produced is not more than 500.
III. : The number of pillows of type B must exceed the number of pillows of type A by
at most 200.
(a) Write three inequalities, other than which satisfy all the above
constraints. [3 marks]
(b) By using the scale of 2 cm to 100 pillows on both axes, construct and shade the region
R which satisfies all the above constraints. [3 marks]
(c) Use graph from 15(b), to find
