☆1 inequalities
[ 1/1Inequality]
Assignment:Find the solution set of inequality 6000 ≤80x+4000-40x ≤6430 .
Question type: Inequality
Solution:
The inequality can be reduced to 2 inequalities：
6000 ≤80 * x + 4000 - 40 * x (1)
80 * x + 4000 - 40 * x ≤6430 (2)
From inequality(1)：
x ≥ 50
From inequality(2)：
x ≤ 243/4
From inequalities (1) and (2)
50 ≤ x ≤ 243/4 (3)
The final solution set is :
50 ≤ x ≤ 243/4
