How much for two items with second one discounted?

Type of calculation: Calculating a discounted value and adding it to the full price.
How to use the calculator:
Step 1: Find the price of the second item. Use the Basic Percentage CALCULATOR ("What is X% of Y?"). The second item is 50% off, so you pay 100% - 50% = 50% of the regular price. Enter 50 [X] and 100 [Y]. It will calculate 50% of 100.
Step 2: Add the full price of the first item (100) to the discounted price of the second item.
The formula:
We want the total for two items: first one is 100, second is 50% off.
Price of second item = 50% of 100
Price of second item = (50 / 100) × 100 = 0.5 × 100 = 50
Total price = Price of first item + Price of second item
Total price = 100 + 50 = 150
