Answer:
$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
