He has to work between the range (of 20,0) and (0,20) points to earn more than $125.
What is inequality?
Inequality is the relationship between two expressions that are not equal, employing a sign such as ≠ “not equal to,” > “greater than,” or < “less than.”.
Given that:-
Liam can work at most 20 hours a week but he needs to earn at least $125. His dog-walking job pays $7 per hour and his job as a car-wash attendant pays $11 dollars an hour. How can he earn $125.
Let the Dog walking hours are represented by x and Car wash hours will be represented by y. The inequality will be formed as follows:-
7x + 11y ≥ 125
x+y = 20
When we plot these two equations on the graph we will get the range for the time from (20,0) and (0,20).
Suppose we will take a random point-like (5,15) when we put this value in the inequality we get the total earning greater than $125.
7x + 11y ≥ 125
7 (5) + 11 ( 15 ) ≥ 125
35 + 165 ≥ 125
200 ≥ 125
Therefore He has to work between the range (of 20,0) and (0,20) points to earn more than $125.
