**Answer:**

**Rodrigo pays $54.00 for the jacket**

**Step-by-step explanation:**

The original price of the jacket = $80.00

Rodrigo buys the jacket that is on sale for off of the original price.

Discount on the jacket = × 80.00 = $20.00

Price after discount = 80.00 - 20.00 = $60.00

Rodrigo has a coupon for an additional 10% off.

The price after redeeming the coupon = 10% × 60.00 = 0.10 × 60 = $6.00

Rodrigo have to pay = 60 - 6 = **$54.00**

**Rodrigo pays $54.00 for the jacket.**
