Answer 1

????

how oft du yu kompount the interest ?????????

If wons a yeer, yu hav 1.055^x=(11,409/5000)=2.2818

x*log(1.055)=log(2.2818)

x=log(2.2818) / log(1.055)

if yuze log10,...log10(2.2818)=0.3582775757952279

log10(1.055)=0.02325245963371156

0.358277.../0.02325245...=15.4081639104073 yeers
