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

B 17.66

Step-by-step 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

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

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 = = $16.8

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

Final price of blouse including sales tax = = $17.66
