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$56.18$.
