What is the final cost of a $499 iPad that has been marked down 20% and includes 7% sales tax?

Step-by-step explanation:

Given that the original price of the TV is $499, the new price after the given percent of change of 10% would be, $548.9. 10% of $499 is $49.9. This is added to the original price. Now, if the increase is 30%, 30% of $499 would be $149.7. Add this to $499 and the new price is $648.7. Hope this answers your question.

Answer:$427.14

Step-by-step explanation:

Multiply $499 and 20% = 99.8

499-99.8=399.2

399.2 multiplied by 7%=27.944

Add 399.2 and 27.944 = 427.144
