Answer:
Price of DVD at Store A = $ 94.5
Price of DVD at Store B = $ 95
Step-by-step explanation:
Given that
Price of DVD player = $ 100
Sales Tax = 5%
Now, lets calculate price of of DVD player at store A
The price of DVD player at store A after 10% discount = 100 - 10% of 100
The price of DVD player at store A after 10% discount= 100 - 0.1x100
The price of DVD player at store A after 10% discount= 100 - 10 = $90
Price of DVD player at store A after sales tax = 90 + 5% of 90
Price of DVD player at store A after sales tax = 90 + 0.05x90
Price of DVD player at store A after sales tax = 90 + 4.5
Price of DVD player at store A after sales tax = $94.5
Now, lets calculate price of of DVD player at store B.
The price of DVD player at store B= 100
Price of DVD player at store B after sales tax = 100 + 5% of 100
Price of DVD player at store B after sales tax = 100 + 0.05x100
Price of DVD player at store B after sales tax = 100 + 5
Price of DVD player at store B after sales tax = $ 105
Price of DVD player at store B $10 rebate = 105 - 10
Price of DVD player at store B $10 rebate = $95
