solution: - as given the annual bonus $p_1$ =$840 increases at a rate of 5% be each year .

⇒ r= 5% =0.05

so, the amount function after x years for this situation will be

$a_1=p_1(1+r)^x\text{where r is the rate of interest}$

$\rightarrow\ a_1=840(1+0.05)^x\\\rightarrow\ a_1=840(1.05)^x[/)now for deposit amount [tex]p_2$ =$840 increases at a rate of 2.5% each year .

⇒ r= 2.5% =0.025

so, the compound amount function after x years for this situation will be

$a_2=p_2(1+r)^x\text{where r is the rate of interest}$

$\rightarrow\ a_2=3000(1+0.025)^x\\\rightarrow\ a_2=3000(1.025)^x[/)so by adding both amount function (1) and (2) we get ,the total amount function after x years will be[tex]y=840(1.05)^x+3000(1.025)^x$

now to plot the graph we have to find points

at x =400,

$y= 840(1.05)^{-400}+3000(1.025)^{-400}$

by taking log on both sides and after solving it we get, y=0

and so
