Step 1 :Given the principal amount (P) is $5300, the annual interest rate (r) is 5% or 0.05 in decimal, the number of times that interest is compounded per year (n) is 4 (since it is compounded quarterly), and the number of years the money is invested for (t) is 8 years.
Step 2 :The formula for compound interest is \(A = P(1 + \frac{r}{n})^{nt}\), where A is the amount of money accumulated after n years, including interest.
Step 3 :Substitute these values into the formula: \(A = 5300(1 + \frac{0.05}{4})^{4*8}\)
Step 4 :Simplify the expression inside the parentheses: \(A = 5300(1 + 0.0125)^{32}\)
Step 5 :Calculate the power: \(A = 5300 * 1.488864\)
Step 6 :Multiply to find the compound amount: \(A = \$7896.98\) (rounded to the nearest cent)
Step 7 :The compound amount after 8 years is \(\boxed{\$7896.98}\)
Step 8 :The amount of interest earned is the compound amount minus the principal: \(Interest = A - P\)
Step 9 :Substitute the values: \(Interest = \$7896.98 - \$5300\)
Step 10 :Calculate to find the interest: \(Interest = \$2596.98\)
Step 11 :So, the amount of interest earned is \(\boxed{\$2596.98}\)
