Programming: Contemporary concepts

Congrats Leron. Also passed all my subjects and yes finally after a long journey I have my degree.by

Was lekker, hopefully also my last one for my degree.by

You are right Leron. It was a bit confusing because they mention overhead per day but the rest per hour. So yes we should read carefully. Thanks for pointing that out. Regardsby

Was a nice one yes. Wish i could say the same for INF3705 and INF3720, they were very tough. Also still have to write my last one tomorrow and pray I have past them all before I see you at graduation.by

Yes you are right. I made the same mistake there with the Total investment rather than the income for the brake even year. Thanksby

Mmm. Nice tip. Time management will be important, lots of work for 80 marks. Thanksby

You are right! I made a mistake there. I devided by total investment enstead of just income for breake even year. How ever for P2 I then get 6-(70000/90000)= 6 - 0.77 = 5.22 What do you think?by
