Since 
represents the number of years passed since 2005, in 2005 we have 
, and in 2015 we have 
. Let 
represent the profits of Jones and Davis, respectively, at year y.
We have
Choosing the best company somehow depends on how much time you can wait: Jones start with a higher value (10 vs 8), but it has a descending trend, because the multiplicative factor 
goes to zero as t grows.
On the other hand, Davis starts with a smaller value, but 
tends to infinity as t grows.
So, if you need an immediate result, the most valuable company is Jones, otherwise you're certain can Davis will eventually become bigger.
More precisely, we have
So, after 11 years, Davis will overcome Jones.
Jesos it’s all pixelated I can’t see anything on mi phone br
It will take 8 minutes.
You use a proportion
5/1=2400/x you use 2400 because 2.4km=2400 meters and u need to use the same unit of measurement.
so cross multiplying gives you 5x=2400 which is equal to 480. BUT this is 48 seconds, and it asks you how many minutes, not seconds. So, you divide by 60 because there are 6 seconds in a minute, and you get 8.
Well it would make sense that Jenny had 6 marshmallows and Julie did not put any in, Hope this helped a little
25•15=365-50=315 so that is the answer
