I'll give you a question, please answer with step-by-step reasoning process.
Ralph has $54.00 worth of products in his cart. At the register, he asks if he could have a 20% discount on an item with a small issue. This item is $20.00 to start. They agree.  Ralph also has a 10% coupon on his purchase, which he uses after the 20% discount on the item with the small issue. How much will all of his items cost?

45
They approved 20% off of the $20.

00 item so.

20 * 20 = $4.

00.

The item has a $4.

00 discount which can be applied from his final total of $54.

00 so 54 - 4 = $50.

00.

Now he can use his 10% coupon on the $50.

00 total so.

10 * 50 = $5.

00.

The total was $50.

00 but his $5.

00 discount now makes it 50 - 5 = $45.

00.

.

Thus, the answer is 45
