Question

A group has more than $120 to spend. The inequality 5x + 20 > 120 represents the cost to rent a hall for a conference, where x represents the number of hours the group can rent the hall. Which of the following is the solution for this situation?

Answer 1

x>20

Explanation:

You want to try and get the x alone so

5x + 20 > 120

-20 -20 Subtract 20 from each side

5x > 100

5x/5 > 100/5 Divide 5 from each side

x > 20
