Answer:
$852
Explanation:
From the given question, the following are given:
Present value, PV = $675
Rate, r = 6% = 0.06
Number of years, n = 2 years
Number of times per year, m = 2
The balance in his account is the future value (FV), so that;
Future value = PV

= 675

= 675 x 1.26248
= 852.174
Future value = $852
Thus, the balance in Alex's account would be $852.
