Let h = amount of hours
Since they earn $7.50 per hour, we can multiply that by an unknown amount of hours to get $116.25. Let's solve:
Divide both sides by 7.5 to isolate the h, amount of hours.
Simplify.
In conclusion, someone would have to work 15.5 hours to earn $116.25 if they earn $7.50 per hour.
