Need the complete answer of this problem.

1. The price is $50.
The discount is 10% of $50.
10% of $50 = 10% * $50 = 0.10 * $50 = $5
The discount is $5
Now we subtract the actual discount to find the final price.
$50 - $5 = $45
The selling price is $45

2. Use the same method as for problem 1. First find the amount of discount by multiplying the percent by the price. Then subtract the amount of discount from the original price.
The price is $500.
The discount is 20% of $500.
20% of $500 = 20% * $500 = 0.20 * $500 = $100
The discount is $100
Now we subtract the actual discount to find the final price.
$500 - $100 = $400
The selling price is $400

3. The price is $80.
The discount is 5% of $80.
5% of $80 = 5% * $80 = 0.05 * $80 = $4
The discount is $4
Now we subtract the actual discount to find the final price.
$80 - $4 = $76
The selling price is $76

I did the first three problems for you.
Now you can try the last two.
Write in the comments what you get for the discount amounts and selling prices of problems 4 and 5, and I'll let you know if you're correct.
