Answer

Round the account balance to two decimal places: $67170.71$

Steps

Step 1 ：Given the principal amount (P) is $59,458, the annual interest rate (r) is 3.5% or 0.035 in decimal form, the number of times that interest is compounded per year (n) is 4 (quarterly), and the time the money is invested for (t) is 3.5 years.

Step 2 ：We use the compound interest formula to find the account balance (A): $A = P {(1 + \frac{r}{n})}^{n t}$

Step 3 ：Substitute the given values into the formula: $A = 59458 {(1 + \frac{0.035}{4})}^{4 * 3.5}$

Step 4 ：Calculate the account balance: A = 67170.71402733811

Step 5 ：Round the account balance to two decimal places: $67170.71$
