Jenny Company produces two types of pants: long pants and short pants. The cost of making a
pair of short pants and a pair of long pants are RM 75 and RM 95 respectively. In one week, the
company must produce at least 150 pants of each type. The minimum weekly production is 500
pants. The short pants are sold for RM 120 each and the long pants for RM 150 each. Using the
graphical method, find:
a. The number of short pants and long pants to be made in a week in order to minimise the
total production cost.
b. The profit made at the minimum weekly production cost.
