How could you represent the large square as a power of 10?

Answer:
Here’s my answer
This means the cost of the item to you is $28.35. You will pay $28.35 for a item with original price of $40.5 when discounted 30%. In this example, if you buy an item at $40.5 with 30% discount, you will pay 40.5 - 12.15 = 28.35 dollars.
