Final answer:
To calculate the net price factor and the net price, subtract the discount percentage from 100%, convert it to a decimal, multiply the original price by this decimal to get the net price before tax, calculate the tax, and add it to find the final net price.
Step-by-step explanation:
To calculate the net price factor using the complement method and then determine the net price, you need to follow these steps:
Begin by calculating the total cost of items before tax or discounts.
If discounts are provided, subtract the discount percentage from 100% to find the complement (the remaining percentage).
Convert the complement percentage to a decimal by dividing by 100.
For instance, if the discount is 20%, the complement is 80%; in decimal form, this is 0.80.
Multiply the original total cost by the complement in decimal form to find the net price before tax.
If tax needs to be applied, convert the tax rate to a decimal and multiply the net price before tax by this decimal to find the amount of tax.
Add the amount of tax to the net price before tax to get the total net price.
Without specific discount or tax rate values, we cannot calculate the exact net price or net price factor.
These calculations would allow you to understand how discounts and taxes affect the final cost of purchases.
