A coat was marked down by 60 percent from its original price of $99. Including an 8 percent sales tax, what is the final cost of the coat? $39.60
$42.77
$59.40
$64.15

Given:

A coat was marked down by 60 percent from its original price of $99.

Rate of sales tax = 8%

To find:

The final cost of the coat after including tax.

Solution:

We have,

Original price = $99

Rate of marked down = 60%

Rate of sales tax = 8%

Marked price = Original price - 60% of original price.

Now,

Final cost = Marked price + Sales tax

Therefore, the correct option is B.
