Answer:
So, the amount invested after 6 years is £1547
Step-by-step explanation:
We can use formula
[tex]A=P(1+r_1)^{t_1}(1+r_2)^{t_2}[/tex]
where
P is money invested
r1 is first interest rate
t1 is time for r1
r2 is second interest rate
t2 is time for r2
[tex]P=1200[/tex]
[tex]r_1=0.03[/tex]
[tex]t_1=2[/tex]
[tex]r_2=0.05[/tex]
[tex]t_2=4[/tex]
now, we can plug values
[tex]A=1200(1+0.03)^{2}(1+0.05)^{4}[/tex]
[tex]A=1547[/tex]
