Leo can buy a certain computer for p1 dollars in State A, where the sales tax is t1 percent, or he can buy the same computer for p2 dollars in State B, where the sales tax is t2 percent. Is the total cost of the computer greater in State A than in State B?
(1) t1 > t2
(2) p1t1 > p2t2

Why?

If "buy a certain computer for p1 dollars" means the price is p1, before tax, then the total cost for the computer in A would be p1+p1t1, and it would be p2+t2p2 in B

Then the answer would be E.

go with E.

price of a computer in state A = p1(1+t1/100)
price of a computer in state B = p2(1+t2/100)

from i,
t1 = 2%, t2 = 1%
if p1=100 and p2 = 105, nothing can be said..

from ii,
t1 = 2%, t2 = 1%
if p1=100 and p2 = 105, nothing can be said..

combining i and ii aslo donot give any answer.

Clearly E because it can be some very different prices modified by huge differences of percentage so it's impossible to get any conclusion with those 2 statements.

However, I found the problem not so clear about tax and "the cost to buy a computer"... :evil:
