start by writing an expression in the form
[tex]A=p\cdot(1+\frac{r}{n})^{n\cdot t}[/tex]the p is the principal which is equivalent to the invesment, the r is the interest rate and the n will be equivalent to the number of periods that will be compounded which in this case will be the 12 months
[tex]A=5,280\cdot(1+\frac{0.042}{12})^{12t}[/tex]now to find the amount on the account after 8 years, replace t as an 8
[tex]A=7384.18[/tex]
