Martha decides to babysit for $6 per hour to earn
money for a concert ticket that costs $25. Which
inequality shows the number of hours, h, she needs
to babysit to earn at least enough money to buy the
concert ticket?
To earn $25, she would have to work a total of 5 hours, to get $30. Although 30 is over 25, 4 hours, or $24 is not enough. H represents hours, so 5 hours, or 5h.
