Answer

Explanation:

Step1: Calculate the price after discount

The original price is $180. The discount is 30%, so the price after discount is (180\times(1 - 30%)). [180\times(1 - 0.3)=180\times0.7 = 126]

Step2: Calculate the price after sales - tax

The sales - tax is 4%. The price after tax is the price after discount multiplied by ((1 + 4%)). [126\times(1 + 0.04)=126\times1.04=131.04]

Answer:

(131.04)
