Question

Martin earns $18 dollars an hour. Which of the following inequalities represents the amount of time martin needs to work to earn at least $78 per day? 18 - t > 78 18+ t < 78 18t > 78 18t < 78

Answer 1

18t >= 78

Explanation:

Not sure if there's an equals sign in the problem that you were given, but there should be. The 18 in the inequality stands for the hourly wage. The t stands for hours worked. 18(wage) x t(hours) has to be greater than or equal to 78 in order for Martin to at LEAST $78 per day. :)
