John wants to buy a dvd player. the price is $100, and the sales tax is 5 percent. store a is offering a 10 percent discount and store b is offering a $10 rebate. what would john's total cost be at the two stores? total cost at store a = total cost at store b =

$94.5

$95

Step-by-step explanation:

To find the total cost of each store, we first need to calculate for the total price together with the discount for Store A and the rebate for Store B.

First we do Store A:

Store A discount = $100 x 0.10

Store A discount = $10

New Price = $90

Sales tax = 5% 0.05

Total Cost Store A = $90 + ($90x0.05)

Total Cost Store A = $94.5

Now for store B:

Store B rebate = $10

Cost w/ Sales Tax = $100 + ($100x0.05)

Cost w/ Sales Tax = $105

Total Cost Store B = $105 - $10

Total Cost Store B = $95

-7/8

instead of subtracting you add the -6/8 and -1/8
