Final answer:
The original total cost of the items is $45.00. Without the discount rate, we cannot calculate the exact discounted total. The total after applying a discount will be less than $45.00.
Step-by-step explanation:
To find out the total cost with a discount, we'll start by calculating the original total cost of the items without the discount. We have two items priced at $20.00 each and one item priced at $5.00. We'll add these together to get the subtotal.
The calculation is as follows: $20.00 (item 1) + $20.00 (item 2) + $5.00 (item 3) = $45.00.
Next, if we apply a discount to this total, we should subtract the discount from the subtotal. However, since the actual discount rate isn't provided in the question, we cannot give a definitive answer. We can conclude that the total will be less than $45.00 after the discount is applied. The student may need to provide the discount rate or check if there was an oversight in the question prompt.
