Walden’s family is shopping for a reclining chair. The chair the family decided on has a retail price of $800 plus 5% sales tax at four stores. Each store is offering a different promotion.

Answer :

A is 800 plus tax, with $75 back
800x1.05 (because it's 5% tax) -75 =$765
B is 800x.90 (because 10% off means he's
paying 90% x.05=$756
C is 800x 95 (because 5% off means he's
paying 95%) =760
So B is the right answer
