Question

Last week a blouse was on sale for $16 this week the price has increased, What is the price this week including sales tax?

Answer 1

The new price including sales tax is B) $17.66.

Explanation:

We are given that a blouse was on sale for $16. Then there was a 5% increase seen in its price along with a 5.1% sales tax.

So after the 5% increase in price, the price of the blouse =
`((5)/(100) *16)+16` = $16.8

Also, adding the sales tax to get find the final price of the blouse:

Final price of blouse including sales tax =
`((5.1)/(100) *16.8)+16.8` = $17.66

Answer 2

B 17.66

Explanation:

What is the increase this week

increase = original price * increase rate

= 16 * .05

.80

New price = original price + increase

= 16+.80

=16.80

Now we need to find the sales tax

tax = new price * tax rate

= 16.80 * .051

= .8568

Which rounds to the nearest cent

=.86

To find the total cost add the new price to the sales tax

Total cost = new price + sales tax

= 16.80 + .86

=17.66
