In most linear programming problems, there are two stages: 1. to interpret the information given as a series of simultaneous
inequalities and display them graphically.
2. to investigate some characteristic of the points in the unshaded
solution set.
Example
A shopkeeper buys two types of cat food for his shop: Bruno at 40c
a tin and Blaze at 60c a tin. He has $15 available and decides to buy at
least 30 tins altogether. He also decides that at least one third of the
tins should be Blaze. He buys x tins of Bruno and y tins of Blaze.
a) Write down three inequalities which correspond to the above conditions.
b) Illustrate these inequalities on a graph.

Can someone help please (C) is the complete of the question ,the one that is in the photo, I would really appreciate yout anwers༼ つ ◕◡◕ ༽つ

Bruno = 16 cans, Blaze = 14 cans

Step-by-step explanation:

Part A gave you the three equations.  

Part B showed you the intersected points --> (16, 14), (20, 10), & (21.4, 10.7)

Part C is giving you the Cost function: C(x, y) =0.10x + 0.20y

Input the intersected points into the Cost function to find the maximum.

C(16,14) = 0.10(16) + 0.20(14)

             =    1.60      + 2.80

             =    4.40

C(20,10) = 0.10(20) + 0.20(10)

             =    2.0      + 2.00

             =    4.00

C(21.4,10.7) = 0.10(21.4) + 0.20(10.7)

                  =    2.14      + 2.14

                  =    4.28

Of the three results we just found, 4.40 is the biggest value.

So, the maximum occurs at C(16,14) = 4.40

                                                  ↓   ↓

                                          Bruno   Blaze

"it's not the heat, it's the humidity".   that's a partly valid phrase you may have heard in the summer, but it's actually both.   the heat index, also known as the apparent temperature, is what the temperature feels like to the human body when relative humidity is combined with the air temperature.   this has important considerations for the human body's comfort.   when the body gets too hot, it begins to perspire or sweat to cool itself off.   if the perspiration is not able to evaporate, the body cannot regulate its temperature.   evaporation is a cooling process.   when perspiration is evaporated off the body, it effectively reduces the body's temperature.   when the atmospheric moisture content (i.e. relative humidity) is high, the rate of perspiration from the body decreases.   in other words, the human body feels warmer in humid conditions.   the opposite is true when the relative humidity decreases because the rate of perspiration increases.   the body actually feels cooler in arid conditions.   there is direct relationship between the air temperature and relative humidity and the heat index, meaning as the air temperature and relative humidity increase (decrease), the heat index increases (decreases).
