Answer:

$87.23.  

Step-by-step explanation:

We are asked to find the amount after 4 years compounded monthly at the rate of 2.8% APR.

We will use compound interest formula to solve our given problem.

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

A = Final amount after T years,

P = Principal amount,  

r = Interest rate in decimal form,

n = Number of times interest is compounded per year.

T = Time in years.

Let us convert our given rate in decimal form.

[tex]2.8\%=\frac{2.8}{100}=0.028[/tex]

Upon substituting our given values in compound interest formula we will get,

[tex]A=78(1+\frac{0.028}{12})^{12*4}[/tex]

[tex]A=78(1+0.002333)^{48}[/tex]

[tex]A=78(1.002333)^{48}[/tex]

[tex]A=78*1.1183669447674708747[/tex]

[tex]A=87.2326216918627282266\approx 87.23[/tex]

Therefore, we will have $87.23 in the account after 4 years.
