Answer: $1292.95

Step-by-step explanation:

Given: The principal investment deposit = P = $6,200

The annual interest rate= 2.37%

The annual interest rate (decimal)  r=0.0237

The number of times that interest is compounded per year

= 12

The number of years the money is invested for= 8 years

The formula for annual compound amount is:

A=P(1+\frac{r}{n})^{nt}\\\\\Rightarrow\ A=6200(1+\frac{0.0237}{12})^{12\times8}\\\\\Rightarrow\ A=6200(1.001975)^{96}\\\\\Rightarrow\ A=6200( 1.2085399)\\\\\Rightarrow\ A=7492.95

The amount she earned = A-P=\$7492.95-\$6200=\$1292.95
