Question 830633: Please help me I'm having trouble with this problem:
You work as a dental assistant where you are given a $0.75 per hour raise each year. In year three, (after two raises), you earn $9.50 per hour.
Write an equation that models your hourly wage, w, in terms of the number of years, n, since you started as a dental assistant.
What was your starting hourly wage as a dental assistant?
Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! If you're now making $9.50/hr after two raises, what were you making last year? $9.50 - 0.75 = $8.75
The year before that, you were making $8.75 - 0.75, or $8.00
.
Putting this into an equation, with w as your starting wage:
9.50 -.75(n-1) = w
.
The reason you use n-1 instead of n is because you get the raise AFTER the first year ["In year three, (after two raises..."]
