First verify it holds for n=1
then you are allowed to assume it holds for n and you can start with the induction step
for n+1 instead of inserting it into the equation, add it to both sides and transform it to the original formula to proof its equality
this equals the original formula if you had inserted n+1, proving the correctness

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.
