The first mechanic made $2000 for 10 hours. And the second mechanic made $1000 for 5 hours. So therefore if you add how much money they both made, how much moola would they be charged? just say something if you don't understand it.
We can solve inequalities to find all values of the variable that make the inequality true. The idea is to get the variable all by itself on one side of the inequality sign so we can easily see the solutions to the inequality.
Hence for any given inequality and for any given number if we put that number in that inequality and see that the given inequality sign holds true than that number will be a solution of the inequality otherwise it is not an solution of the inequality.
