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

Answer:

[B] $17.66

Step-by-step explanation:

Price increase = 5 % × old price

                        = 0.05 × 16

                        = $0.80

New price = old price + price increase

                 =   16 + 0.80

                 = $16.80

Sales tax = 5.1 % × new price

               =   0.051 × 16.80

               = $0.86

Price + tax

= 16.80 + 0.86

= $17.66

The total price of the blouse is $17.66.

Answer 2

Answer:

The correct answer option is B) $17.66.

Step-by-step explanation:

We know that the original price of the blouse before increase was $16. There was a 5% increase seen in the price along with 5.1% sales tax.

So after 5% increase, the price of shirt = $(\frac{5}{100} *16)+16$ = $16.8

Adding the sales tax to this price to find the final price of the blouse after the increase in price:

Final price of blouse = $(\frac{5.1}{100} *16.8)+16.8$ = $17.66
