28*1.07=29.96 total cost including tax

لكن الجزء الثاني مش واضح اي يبي بالضبط او الاختلاف اللي يبيه ..!!:con2:

first case:
28 * 1.07 = 29.96$

so 29.96 is the first answer
which tells us the the tax is 1.96$ at this first case

second case:
in case we have two bills each with 20$ ,,

20 * 1.07 = $21.4
which tells that the tax is 1.4 * 2 = 2.8
(we multibly by 2 coz we have two bills)

which on this case the tax is 2.8

so we observe that the second case we will get more tax than the first case ,,

p: ان شاءالله يكون لو ربعه صح ،،

الي فهمته ان المسئله تقارن لو عندك فاتوره ب ٢٨ دولار كم يكون التاكس حقها

و لو كان عندك فتورتين كل وحده ٢٠ دولار شلون بيكون شكل التاكس ،،

بالتوفيق

You wont get any change because once you multiply the bill by 1.07 as the computer did you would get a price including tax over the 20 dollars therefore you are requested to top up your money with 9.96 dollars to be able to pay the full amount
