Solution:

a=100000 Kc q=1+1.5/100=203200=1.015 d=20.12.5.5. d=229 d  x=a qd/360=100000 1.015229/360=100951.58 Kca=100000 \ \text{Kc} \ \\ q=1+1.5/100=\dfrac{ 203 }{ 200 }=1.015 \ \\ d=20.12. - 5.5. \ \\ d=229 \ \text{d} \ \\ \ \\ x=a \cdot \ q^{ d/360 }=100000 \cdot \ 1.015^{ 229/360 }=100951.58 \ \text{Kc}
