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

[B] $17.66

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

The correct answer option is B) $17.66.

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 =
`((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 =
`((5.1)/(100) *16.8)+16.8` = $17.66
