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
