Final answer:
The final cost for the hat would be $15.10 after a 13% discount and 8.5% sales tax.
Step-by-step explanation:
To find the final cost of a hat that originally costs $16 with a coupon for 13% off and sales tax of 8.5%, follow these steps:
- Calculate the discount amount by multiplying the original cost ($16) by the discount rate (13% or 0.13). The discount amount is $2.08.
- Subtract the discount amount from the original cost to find the discounted price. The discounted price is $13.92.
- Calculate the tax amount by multiplying the discounted price ($13.92) by the sales tax rate (8.5% or 0.085). The tax amount is $1.18.
- Add the tax amount to the discounted price to find the final cost. The final cost is $15.10.
