A. You have two inequalities:
If you multiply the first inequality by positive number 4 (multiplying inequality by positive number doesn't change the inequality sign), then you get the inequality

B. You have two inequalities:
If you multiply the first inequality by negative number -4 (multiplying inequality by negative number changes the inequality sign), then you get the inequality

Answer:
Step-by-step explanation:
First it base times height times (1/2)
The base is 7 boxes
The height is 5 boxes
A=(7)(5)(1/2)
A=(35)(1/2)
A=17.5
To find 86% of 50, you do 50*.86 (because .86 is the decimal form of the percentage 86%)
50*.86=43 people
