Quiz: Which salad do I eat today?
I can make two kind of dishes
 Tomato and Mozzarella and
 Mushroom and Radish.
I get 10 degree of satisfaction if I eat
tomato and mozzarella
while I get 8 degree of satisfaction if I eat
mushroom and radish.
I also have to prevent myself from growing fat and being high blood pressure
by restricting the energy and
the salt of the relish
to 100kcal and 0.5g per one day respectively.
In order to obtain the maximum degree of satisfaction,
how many times per one week can I take each of the dishes?

Tomato and Mozzarella 
Mushroom and Radish 
upper bound / week 
Energy/dish  279kcal  119kcal  700kcal 
Salt/dish  0.18g  2.8g  3.5g 
degree of satisfaction  10  8  
Let
x_{1} and x_{2} be the times I can take
tomato and mozzarella and
mushroom and radish per one week respectively.
Then, the problem will be formulated as:
maximize  z  = 
10x_{1}  +8x_{2} 
subject to   
279x_{1}  +119x_{2} 
<=  700 
  
0.18x_{1}  +2.8x_{2}  <=  3.5 
  
x_{1}>=0,  x_{2}>=0   
By using the simplex algorithm:
we obtain an optimal solution
z=29.17 when x_{1}=2.03, x_{2}=1.12.
In other words, I can obtain the maximum degree of satisfaction 29.27
when I take about two dishes of tomato and mozzarella
per week and about one dish of mushroom and radish
per week. Other days of the week are the Sabbath of my liver.
