Answer all questions.
11. Product Mix Decision Whoppy Soft Drinks The
production manager for the Whoppy soft drink
company is considering the production of 2 kinds of
soft drinks: regular and diet The company
operates one "8 hour" shift per day. Therefore, the
production time is 480 minutes per day. During the
production process, one of the main ingredients,
syrup is limited to maximum production capacity of
675 gallons per day. Production of a regular case
requires 2 minutes and 5 gallons of syrup, while
production of a diet case needs 4 minutes and
3 gallons of syrup. Profits for regular soft drink are
Rs. 3.00 per case and profits for diet soft drink are
Rs. 2.00 per case.
Write the formulation for this linear program.
Or
A computer retail store sells two types of flat screen
monitors: 17 inches and 19 inches, with a profit
contribution of Rs. 300 and Rs. 250, respectively.
The monitors are ordered each week from an
outside supplier. As an added feature, the retail
store installs on each monitor a privacy filter that
narrows the viewing angle so that only persons
sitting directly in front of the monitor are able to
see on-screen data. Each 19" monitor consumes
about 30 minutes of installation time, while each
17" monitor requires about 10 minutes of
installation time. The retail store has
approximately 40 hours of labor time available each
week. The total combined demand for both monitors
is at least 40 monitors each week.
How many units of each monitor should the retail
store order each week to maximize its weekly profits
and meet its weekly demand?
