Final answer:
To find the final price of an item after a discount and sales tax, you calculate the discount, subtract it from the original price to get the discounted price, calculate the sales tax on the discounted price, and then add the sales tax to the discounted price.
Step-by-step explanation:
The question involves calculating the final price of an item after a discount and including sales tax. To solve this, we take the following steps:
- First, calculate the amount of discount by multiplying the original price by the discount rate.
- Subtract the discount from the original price to get the discounted price.
- Then, calculate the sales tax by multiplying the discounted price by the sales tax rate.
- Finally, add the sales tax to the discounted price to get the final price of the item.
For example, if Emily bought a jacket for $85 and the sales tax is 7.5%, we would calculate the total cost as follows:
- Calculate the sales tax by converting the percent to a decimal (7.5% becomes 0.075) and multiplying by the jacket's price: $85 * 0.075 = $6.375.
- Round the sales tax to the nearest penny: $6.375 is rounded to $6.38.
- Add the original price of the jacket to the sales tax: $85 + $6.38 = $91.38.
Using a similar approach, you can calculate the final price of the 1-Pad cover from the Apple Store.
