Three and one hundred forty one hundredths <span />
No because if you divide 1.25 by two to find out what the half is in 2.5, it would be .62… and since she wants to buy 2.5 pounds, you've already figured out the .5, so 1.25x2 + .62, it would be 3.12.

By definition, we have to
1 AU = 1.5 * 10 ^ 8Km
a comet is 2.3 AU from the earth, which means that we must transform this unit to kilometers.
2.3 AU = (2.3) * (1.5 * 10 ^ 8) = 3.45 * 10 ^ 8km
answer
<span> 3.45 × 10,superscript,8,baseline, km

Let the original price of headphone = x
there is 40% discount which is 0.40x
so the payment price will be x-0.40x = 0.60x
Given that paid amount is $36
so both will be equal
0.60x = 36
x=36/0.60
x=60
Hence final answer is $60.
