Sally picks 30 seashells on Monday. On Tuesday, she picks half as many seashells as she did on Monday. If she can sell each seashell for $1.20, how much money can she make if she sells all of her seashells? Give me reasons, before answering the question

On Tuesday, Sally picks 30 / 2 = 15 seashells. In total, Sally picks 30 + 15 = 45 seashells. The total amount of money Sally can make is 45 * $1.20 = $54. So the final answer is 54.
