Orders are a, b, c, lets write equations to represent the problem's info:
a + b = 150
b + c = 100
a + c = 150
so we have 3 unknowns and 3 equations, so we can solve.
<span>Use the first equation:
a + b = 150
</span>a = 150 - b
and substitute in the 3rd:
<span>a + c = 150
</span>150 - b + c = 150
then
b = c
and we can substitute that in the original equation:
<span>b + c = 100
</span>2b = 100
b = 50
c = 50
and substitute in the first equation:
<span>a + b = 150
</span>a = 150 - b = 150 - 50
a = 100
then a = 100, b = c = 50

Answer:
B. Data analysis
Step-by-step explanation:
Data analysis is a process of inspecting, cleansing and organizing , transforming and modeling data with the goal of discovering useful information, informing conclusion and supporting decision-making.
What is a Data?
Data are information, usually numerical, that are collected through observation, data is a set of values of qualitative or quantitative variables about one or more persons or objects.
Examples of data types are
1. Qualitative
2. Quantitative
3. Attribute
4. Discrete
5. Continuous Data
So this is what you can do count to four four time
