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:
[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:
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 = [tex](\frac{5}{100} *16)+16[/tex] = $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 = [tex](\frac{5.1}{100} *16.8)+16.8[/tex] = $17.66
