Final answer:
To find the total cost, calculate the discount, find the sale price, calculate the sales tax, and add it to the sale price.
Step-by-step explanation:
To find the total cost of the jacket, we need to calculate the discount and the sales tax.
- First, calculate the amount of the discount by multiplying the original price ($85) by the discount rate (20%). The discount is $17.
- Subtract the discount from the original price to find the sale price. The sale price is $85 - $17 = $68.
- Next, calculate the sales tax by multiplying the sale price ($68) by the sales tax rate (8%). The sales tax is $5.44.
- Finally, add the sale price and the sales tax to find the total cost. The total cost is $68 + $5.44 = $73.44.
The correct answer is option B) $74.20.
