Hey
this is in regards to learning curve
first unit takes 25 hours to produce and there is a learning rate of 75%
how long will it take to produce addtional 7 units?
Please help?
200hours
175 hours
84 hours
59 hoursi keep getting 84 hours.
if you explain this in abit more detail i will appreciate it
thank you
November 30, 2014 at 5:07 pm #214802for me i used this formular
y=ax^b
y= 25* (the 8th unit)^-0.4150 and gave me 59.25. nearest hour 59hrsNovember 30, 2014 at 5:23 pm #214805i got the b=-0.4150
*=b
this is what i do in the calculator
8*= times 25
and than i end up with 10.86 times that by 8 end up with 84
November 30, 2014 at 6:23 pm #2148277 units or 7 more units? if the second it should be
(25 X 8^log0.75/log2) X 8 =84 is the total of 8 units but we looking for 7 more unit so we have to reduce the first unit time
84-25= 59 hoursNovember 30, 2014 at 8:16 pm #214887It said 7 units josy87.
I have understood what you have said.
What will the answer be for 7 units??

84 is for 8 units. you then need to deduct the hours for the 1st unit (25 hrs) and you will be left with the hours taken for the next 7 units.
Hope that helps.
November 30, 2014 at 9:08 pm #214902Oh
Yes makes sense now!
Thank you!
December 1, 2014 at 8:52 am #214991Although you can use the formula, it is rather easier to use the doubling rule!!
Making another 7 means that in total you will be making 8.
The average time for 8 units will be 25 x 0.75^3 = 10.546875
So the total time for 8 will be 84.38Then you carry on as per the answers above.
(It doesn’t matter whether you use the doubling rule or the formula, but make sure you know the doubling rule because you could be specifically tested on it)
December 1, 2014 at 2:59 pm #215156Thank you everyone!
Hope I done good on it..
Not going to discuss the answer as it’s pointless. Can’t do anything about it now.
Time to move on to F8!!!
December 1, 2014 at 3:36 pm #215204Sam: I have deleted one line of your post. The reason is that the ACCA ask us to remove posts saying what was in the exam until 17:00 UK time (because some people are still taking the exam in parts of the world).
December 1, 2014 at 3:53 pm #215213Oops
I’m sorry I didn’t know this.
December 1, 2014 at 8:14 pm #215457No problem 🙂
