I also chose Brunei dollars but I'm not sure.

When I changed 6e according to the exchange rate, I got $11.4
When I changed dollars into the exchange rate, I got 6.04e.

So, I thought dollars was cheaper then, than the original price.

As for the closing time, I think it was 17 00.

hi guyz
im not sure about the answer but this is my theories:
i choose Euro because:
the question is he pay 6 euro or 11.5 dollar, which one does he pay less.
the exchange rate is 1 euro = 1.9.... dollar
so I choose to convert euro to dollar
6 * 1.9 =11.4 so 11.4 < 11.5 so 6 euro is lower !!!

and

about the closing time:
they said it will close 4% later than the total time so
the total time is 100 so 4% of 100 is 4.
add the closing time of Sunday (which is 13 00) with 4
u will get 17 00.

about the irrational:
they said to write 2 ???
i wrote "pie" only :(

first while solving paper i too wrote only pie, then while checking i saw which of the following numbers are irrational.
number are hmmmm, then i thought sqare root of 3 +sqare root of6 looks like irrational too, so i wrote it.

About the money thing, what I thought was...

The meal costs 6 euros and $11.5 (they should be linked through an exchange rate, too, I think, as far as my logic is concerned :p...)
When you apply the exchange rate...
Changing 6e to $ you get 11.4
Changing $11.5 to e you get 6.04

So, 6.04 euros and $11.4

I thought it was $'s then, that was less in this exchange rate...?

about the function
the last one they told us to simplify it and i got
2^2x+2
what about u guyz??

Smile u took the question wrong!!
they ask u if he pay with the money 6 euro or with the money $11.5 ,
which is less??(only these two not 11.4)
11.4 is the $ u convert 6 euro to so $11.4=6 euro
so 11.4 < 11.5
so 6 is less than $11.5 (only concern about these two value not the converted ones)

I got that too, but I thought it should be 4^2x+2 ... And last moment thinking, I crossed it out, so I don't know what they'll understand.

Working out will at least give some marks *shrugs*

There were a few mind-boggling, twisting q's :/

I understand your logic on the money one, it was kind of tricky, after the exam, 2 of us were saying dollars, the other two were saying euros :p

It never said to write 2, that was the problem, but it was two marks. The answer space seemed to indicate one answer only.. Another confusion :s

Hope for the best, though, Inshallah :)
