How did people get 30 for last graphs and relations answer where it wants the value of K, me and a few people got 100 for K

[SwirlyPOOF]

I got the same total. I just crashed activities on the critical path.

Cool, was thinking I mucked up after talking with mates

Was the time for the cargo 246 hours?

So does anyone know the answer to the last matrices question and is confident it's correct?
I need to know hahah 

[Tadd12345]

Anyone recall what they got for last question of networks? I think I got around $12500 for the cost of crashing.

Soz bro, the total cost was $12000 for minimum time to reduce. You probably crashed K twice, which is what a lot of people did

Yep you're right I crashed K twice. Damn. Well that's alright I already had a feeling I mucked up 

[Tadd12345]

I got the same total. I just crashed activities on the critical path.

Nah, for one, there was a cheaper alternative to crash two activities which was cheaper than the cost of crashing K again.
Total cost of $12000.
The crashing of the two activities G and H cost $3500 and reduced the critical path by 1, while crashing activity K cost $4000

Yup same here  Jeez I never even saw the 1 June and 11 June and just assumed it was a day apart  Until 2 mins before the end of the exam that is. Putting 10 days n 6 hrs in hours just made me question so hard.

Same, was confused since matrix B differs each time, wondering why they didn’t use different letters to denote it
Completely forgot the context but Got dis answer on my cas. Just hope I copied it correctly!

Yeah that nearly baited me into getting the wrong answer as well. Luckily I noticed last minute
