in oak grove, erik bought a mattress that was marked down 70% from an original price of $500. if the sales tax in oak grove is 8%, what was the total cost of the mattress?

Answer

Explanation:

Step1: Calculate discounted price

The discount amount is $500\times70% = 500\times0.7=350$. The discounted - price is $500 - 350=150$.

Step2: Calculate sales - tax amount

The sales - tax amount is $150\times8%=150\times0.08 = 12$.

Step3: Calculate total cost

The total cost is the discounted price plus the sales - tax amount, so $150 + 12=162$.

Answer:

162
