Answer:

$20.60

Step-by-step explanation:

Price before discount = $21

Discount rate = 10% or 0.1

Discount in dollars = 0.1* 21 =  $2.1

Price after discount = $21 -$2.1 = <em>$18.90</em>

If sales tax is 9% or 0.09

amount of tax  will  be = 0.09 * 18.90 = <em>$1.701</em>

Total price of the phone including taxes = Price before tax + tax amount;

Total price = 18.90 +1.701

                 = 20.601

Therefore total price will be $20.60

3(1/3)b = 3(1/4)
