Answer 1

Its B

Explanation:

Answer 2

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.

`\text{Marked price}=99-(60)/(100)* 99`

`\text{Marked price}=99-59.4`

`\text{Marked price}=39.6`

Now,

Final cost = Marked price + Sales tax

`\text{Final cost}=39.6+(8)/(100)* 39.6`

`\text{Final cost}=39.6+3.168`

`\text{Final cost}=42.768`

`\text{Final cost}\approx \$42.77`

Therefore, the correct option is B.
