Give the step-by-step reasoning process and then the final answer. 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 = $6.
The final answer: 6.
