Final answer:
To find the final sale price of a Chromebook originally priced at $360 with a 30% discount and a 10% sales tax, calculate the discount, subtract it from the original price, then add the sales tax to find that the final sale price is $277.20.
Step-by-step explanation:
The student has asked for calculating the final sale price of a Chromebook after a discount and sales tax have been applied. The original price of the Chromebook is $360. To find the final sale price, we first need to calculate the discounted price, and then add the sales tax to it.
- Calculate the discount amount: $360 × 0.30 = $108.
- Subtract the discount from the original price: $360 - $108 = $252.
- Convert the sales tax rate to decimal form: 10% = 0.10.
- Calculate the sales tax on the discounted price: $252 × 0.10 = $25.20.
- Add the sales tax to the discounted price: $252 + $25.20 = $277.20.
The final amount you pay for the Chromebook, after applying a 30% discount and adding a 10% sales tax, is $277.20.
