Python practice: Variables & Data Types

Create a variable price = 250 and quantity = 3. Multiply them to compute total and print total:

Create units = 15 and rate = 45.5. Print type(units) on the first line and type(rate) on the second line:

Given raw input strings raw_price = "450" and raw_tax = "81", cast them to integers and print their numeric sum 531:

Convert decimal margin = 0.25 into a string using str(margin) and print f"Margin: {str(margin)}":

Initialize balance = 1000. Add 250 using +=, then add another 100 using +=. Print balance:

Create a boolean flag is_delivered = True. Print the variable and its type on separate lines:

Create three variables: unit_cost = 80, sales_tax = 14, and final_price = unit_cost + sales_tax. Print final_price:

Given revenue = 50000 and cogs = 35000, compute gross_profit = revenue - cogs and margin_pct = gross_profit / revenue. Print margin_pct:
