Thank you!

You might want to review the definitions of the variables in the compound-interest formula...?

. . . . . $A\, =\, P\left(1\, +\, \frac{r}{n}\right)^{nt}$

. . . . .A: ending value or balance
. . . . .P: beginning value or balance
. . . . .r: interest or growth rate, expressed as a decimal
. . . . .n: number of compoundings per interest term (yearly, in this case)
. . . . .t: number of terms (years, in this case)

How are you arriving at 370 compoundings per year...?
