Convert the following information into a pie chart and a line chart for the years 1980-1989. While the sales of hardback books has decreased in recent years due to the digital
availability of novels, people still enjoy the feel of a physical book in their hands. In the 1980s sales of hardback books were at their highest. The number of hardback books sold in the US was 18.5 million in 1980. This number steadily increased by 1.2 million in 1981 and 2.2 million in 1982. The peak of sales for hardback books came in at 28.4 million in 1988. The numbers were steady for 1983 and 1984 at 22.4 million. 1985
showed a slight decrease in sales of 1.1 million; however, 1986 and 1987 were on the
rise and steady at 25.8 million each year. By 1989, sales of hardback books fell off to 26.4 million and remained steady throughout the 1990s.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
