I just ask a question about some javascript and the answers I received are not working unfortunately. From the code attached 600 for investment, 5 for growth and 4 for time should give 630, 1291.50, 1986.50, and 2715.08 in order form year 1 to 4. Instead I am getting (see table). This the formula:

first year: B(1) = p* (1 + i) second year: B(2) = (p + B(1)) * (1 + i) third year: B(3) = (p + B(2)) * (1 + i) the t-th year: B(t) = (p + B(t-1)) * (1 + i)

Year	Principal	Balance
1	600.00	7200.00
2	7200.00	46800.00
3	46800.00	284400.00
4	284400.00	1710000.00
