a dvd player was marked down by 30 percent from its original price of $75. including a 7 percent sales tax, what is the final cost of the dvd player?\n$22.50\n$24.08\n$52.50\n$56.18
Answer
# Answer:
D. $\$56.18$
# Explanation:
## Step1: Calculate the discounted price
The discount is $30\%$ of $\$75$. The amount of the discount is $0.3\times75 = 22.5$. The discounted - price is $75−22.5=\$52.5$.
## Step2: Calculate the price with sales tax
The sales tax is $7\%$ of the discounted price. The amount of the sales tax is $0.07\times52.5 = 3.675$. The final cost is $52.5 + 3.675=\$56.175\approx\$56.18$.
