Question 1045274: A courier company, Weka Couriers, currently delivers four million packages per year and estimates that this will increase by 5% each year. Its deliveries can be modelled by the equation y= 4* (1.05)^t where y is the number of packages delivered in millions, and t is number of years since 2011.
i) How many packages do you expect Weka couriers to deliver in 2012?
ii) How long will it take for the number of packages delivered to reach 8 million?

y= 4%2A+%281.05%29%5Et+
a. in 2012 it is 1 year since 2011 t=1
y= 4%2A+%281.05%29%5Et+
y= 4%2A+%281.05%29%5E1+
y= 4%2A+1.05+

b. means when y=8
8= 4%2A+%281.05%29%5Et+
2= +%281.05%29%5Et+
