Hey there!
Here are the steps involved in answering this question:
1. We know that 36 handbags were sold for $1620 during the sale.
2. We want to know how much money they earned by selling 36 handbags for 49 dollars each.
Steps:
1. Since 36 handbags were also sold before the sale, multiply 49 by 36.
36 x 49 = 1764
They earned $1764 before the sale.
Now, find the difference between each of the sales.
1764 - 1620 = 144
Answer: $144
