Answer:
250 - 20 < 80 + 15x
Step-by-step explanation:
Given that
Beth has 250 books and 20 books sold each week
While on the other hand, Martin has 80 books and sell 15 books each week
Let us assume each week be x
Now the equations are
Beth 250 - 20x
Martin 80 + 15 x
Now the inequality would be
250 - 20 < 80 + 15x
Answer:
the graph in the attached figure
Step-by-step explanation:
we have
isolate the variable y
Subtract 7x both sides
Divide by 3 both sides
The solution of the inequality is the shaded area below the dashed line
The equation of the shaded line is
The slope of the dashed line is negative
The y-intercept of the dashed line is the point
The x-intercept of the dashed line is the point
To graph the inequality plot the intercepts and shade the area below the dashed line
using a graphing tool
