[tex]A=6000(1+0.05)^{2.5}=$6,778[/tex]

The approximate value of the account after 2.5 years is $6,778.

Option d is correct.

Compound Interest:

The amount is given by,

                    [tex]A=P(1+\frac{r}{100} )^{n}[/tex]

Where P is Principle, r is rate of interest and n is time.

Given that,  P=6000, r = 5% and t= 2.5 years

Substitute values in above formula.

             [tex]A=6000(1+\frac{5}{100} )^{2.5}\\ \\A=6000*(\frac{21}{20} )^{2.5}\\ \\A=6778[/tex]

The approximate value of the account after 2.5 years is $6,778.
