73Percent off, then tax

A jacket's regular price is 60 dollars. It is on sale for 25% off, and then an 8% sales tax is added to the sale price. What is the total cost of the jacket, in dollars? A) 45.00 B) 48.60 C) 49.80 D) 64.80

The total cost is $48.60, answer B. The 25% discount brings $60 down to $45, then 8% tax on $45 adds $3.60 more, giving $48.60.
