Hey Geust, I think none of the answers are correct.
If Weslet earns $6.50 an hour at the Bames and Noble bookstore, then the money he earns will be depending on X.
X is the number of hours he worked, and Y is the number of money he earned.
We then see the equation unfold. $6.50 an hour for X hours is Y.
We transfer this word phrase into an equation to get
$6.50x = y
Please tell me if I am incorrect. I hope this helps!
