Sagot :

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.

[tex]\text{Marked price}=99-\dfrac{60}{100}\times 99[/tex]

[tex]\text{Marked price}=99-59.4[/tex]

[tex]\text{Marked price}=39.6[/tex]

Now,

Final cost = Marked price + Sales tax

[tex]\text{Final cost}=39.6+\dfrac{8}{100}\times 39.6[/tex]

[tex]\text{Final cost}=39.6+3.168[/tex]

[tex]\text{Final cost}=42.768[/tex]

[tex]\text{Final cost}\approx \$42.77[/tex]

Therefore, the correct option is B.
