A coat was marked down by 60 percent from its original price of 99 dollars Including an 8 percent sales tax, what is the final cost of the coat?

A 60% markdown means the coat costs 40% of its original price: $99 × 0.40 = $39.60. Add 8% sales tax by multiplying by 1.08: $39.60 × 1.08 = $42.768, which rounds to $42.77. The correct choice is A, $42.77.
