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
