She did sell the newspapers for $.25 each at age 80. The equation is referred to as a linear equation in one variable if only one variable is present in the linear equation.
<h3>A linear equation is what?</h3>
It is described as the relationship between two variables, and a straight line results from plotting the graph of the linear equation.
The information provided in the issue is;
One newspaper will set you back $.25.
Other newspapers are $.40 each.
The 100 newspapers were purchased for $28.00.
x is the quantity of newspapers sold for $.25 each.
Y stands for the other newspaper's number.
The total of both newspapers is one hundred.
x+y=100
y=100-x
25x+ 40y=28.00
25x+40(100-x)=2800
25x+4000-40x=2800
-15x+4000=2800
-15x=-1200
x=80
She therefore sold 80 newspapers for $.25 each.

Answer: A rotation about 270 degrees CW about the origin and 90 CCW about the orgin.
Step-by-step explanation: Using the rules of 90 degrees Counterclockwise
(x,y)⇒( -y,x)
D is 3,2 then it goes to -2,3 which were A is
E is 3,7 then it goes to -7,3 which C is at
F is 10,5 then it goes to -5,10 where B at.
Also it 270 CW because 270 CW is the same as 90 CCW.
