total cost will be 250 +( 6.75 /100 x $250) sales tax
= $250 + $16.875
=$266.875
B. cost of the stereo from online store
=price $235 plus sales tax at 6% plus shipping cost $9.95
6% of sales = 6/100 x 235 =$14.1
Total cost = $235 + $14.1 + $9.95
=$259.05
The online store has a better deal.
One advantage of buying from a store is after sales service. Once you buy the stereo, you will be allowed to test if its working as should be. The staff at the store will demonstrate how to operate the stereo.

Total cost = $149.99 +$9.49+$6.99= 166.47
cost of the headphones will be $166.47
