Overview: 2 questions will be solved this time.Among them
☆2 inequalities
[ 1/2Inequality]
Assignment:Find the solution set of inequality 240a+200(20-a) >4500 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
240 * a + 200 * ( 20 - a ) >4500 (1)
From inequality(1)：
a ＞ 25/2
The final solution set is :
a ＞ 25/2
[ 2/2Inequality]
Assignment:Find the solution set of inequality 12a+10(20-a) <230 .
Question type: Inequality
Solution:
The inequality can be reduced to 1 inequality：
12 * a + 10 * ( 20 - a ) <230 (1)
From inequality(1)：
a < 15
The final solution set is :
a < 15
