The interest does not compound, but multiplied by the number of periods.
If the initial capital is C=350, the interest rate is r=0.015, and the number of periods is n=2, we can calculate:
[tex]FV=C(1+nr)^{}=350\cdot(1+2\cdot0.015)^{}=350\cdot1.03=360.50[/tex]After 2 years, he will have $360.50 in his account.
