Megan pays $16 for a shirt that costs $22 before sales. What is the amount of the discount?
Let x be the amount of the discount.
We have, 22 - x = $16.
We change the writing of the equation:
22 - x + x = 16 + x.
So, 22 = 16 + x.
We then Remove 16 from both sides:
22 - 16 = 16 + x - 16.
So, 22 - 16 = x.
So, the amount of the discount is x = $
