What are points worth to you? I'd just buy $100 of vouchers and get the $181 and $125 fares, and abandon $3.

Oh yeah, I'd definitely like to be earning. But free money is free money.

Only you have the data to rule out the remaining options.

You guys pretty much have the same numbers as me. I thought about your option about 15 minutes after posting the problem, it's a good option. Suppose $181 flight ($27 remainder) and $350 voucher would leave $1.

I assume this is not your own real experience (e.g. child)?

I guess if it was part of the marking criteria, fair enough. I did Business Principles in grade 9. From the second exam onward, we were required to supply our own blank paper for answering the exam. Strict guidelines were prescribed to us as to how the page must be set up (e.g. rule the top and bottom and a margin of 2 cm, all in red pen; rule off the answer to every question with a red line; ruler used to rule lines must have absolutely no dents in it; etc. etc.). Every violation of the guidelines attracted a -0.5 point penalty; the number of penalty marks that could be accumulated as such was unbounded. Though no one had ever got a negative score due to having too many violations, there were people who had answered the test otherwise perfectly but scored a less than perfect mark due to guideline penalties. A friend of mine aced a test once but scored the full marks minus 0.5 points. The reason was because he wrote out something which was a mistake, so the correct way to edit it is cross it out with a straight ruled line, then write the replacement text above or to the side. He lost the mark because he wrote his corrected text in the margin.

Here's a math puzzle to drool over:

The answer is 110.

Re: The totally off-topic thread

The answer is 110.

I got 101. Don't forget BODMAS.

Re: The totally off-topic thread

105 but making an assumption.

No - think he interpreted two flowers on last line. My assumption is that two yellow flowers (middle line) is double one yellow flower on bottom line.

And now its gone!

Re: The totally off-topic thread

hints:
3rd row has 2 yellow flowers
2nd row and 3rd row have blue flower with 5 petals
and of course, bodmas

Red 20
Blue 5
Yellow 1

1 + 20 x 5
=1 + 100
=101

Multiplication and division come before addition and subtraction. And they are all preceded by calculating brackets and 'of'.

Red 20
Blue 5
Yellow 1

1 + 20 x 5

pretty close!

Actually fat fingers are to blame for transposing the figures.

I wouldn't take the number of petals on the flower as significant. The number of petals on the red or yellow flowers have no correlation with their value.

I took the blue flower to have a consistent value.

However if it is 4 in the last line, then the answer would be 81. YMMV

That's the answer!
