Question

Jacob paid $120 for a new phone. The store gave him a 15% discount for being a new customer. He also needs to pay a sales tax rate of 8%. How much did he pay for his new phone?

a) $112.80
b) $132.00
c) $102.60
d) $128.40

Answer 1

To calculate the final price Jacob paid for the phone, a 15% discount is subtracted from the original price, and then an 8% sales tax is added to the discounted price. The calculation shows a final amount of $110.16, however, this is not an option provided, suggesting a typo in the question. The closest option to the calculated price is (c) $102.60.

Step-by-step explanation:

The question involves calculating the final price of a phone after taking into account a discount and adding sales tax. To find the discounted price of Jacob's new phone, we first calculate the discount amount and subtract it from the original price. Then, we calculate the sales tax on the discounted price and add it to find the total amount paid.

To calculate the discount: $120 × 0.15 = $18. So, the discounted price is $120 - $18 = $102. To calculate the sales tax: $102 × 0.08 = $8.16. Therefore, the final price Jacob paid for the phone is $102 + $8.16 = $110.16.

However, since this is not one of the provided options, there might be a miscalculation or typo in the question. Based on the method, if we consider the closest option to the calculated amount, the answer would be (c) $102.60.
