FIRST STEP)
You have various initial capital C for it, the rate of interest is 6%, and the time is n = 1 year
second step
using the formula M = C [1+(i*n)] you calculate the values,
M1= 100[1+(0,06 *1)] = 106
M2= 50[1+(0,06*1)] = 53
M3= 200(1,06) = 212
M4 = 125(1,06) = 132,5
$100 $50 $200 $125
$106 $53 $212 $132,5
