The manufacturer’s suggested retail price (MSRP) of a certain item is $60. Store A sells the item for 20 percent more than the MSRP. The regular price of the item at Store B is 30 percent more than the MSRP, but the item is currently on sale for 10 percent less than the regular price. If sales tax is 5 percent of the purchase price at both stores, what is the result when the total cost of the item at Store B is subtracted from the total cost of the item at Store A?
Options:
A) $ 0	B) $ 0.63	C) $ 1.80	D) $ 1.89	E) $ 2.10

Rationale: msrp = 60 price at store a = 60 ∗ 120100 = 72 = 60 ∗ 120100 = 72 price at store b = 60 ∗ 130100 ∗ 90100 = 70.2 = 60 ∗ 130100 ∗ 90100 = 70.2 difference = 72.0 - 70.2 = 1.8 sales tax applicable = 5 % on both = 1.8 + 0.09 = 1.89 answer = d
Answer: D
