Question

Sa presupunem ca ai 100 lei intr-un cont de economii ssi banca adauga 10% pe an in cont. Cati bani ai avea in cont peste 5 ani daca nu ai retrage deloc bani din cont

Answer 1

dobanda simpla
100+5*(10/100)*100=100+5*10=150lei

dabanda compusa
100(1+10/100)^5=100*1,1^5=100*1,61051=161,051 lei≈161,05 lei

Answer 2

$1\not0\not0\,lei\cdot \frac{11\not0}{\not0\not0}\cdot \frac{11\not0}{1\not0\not0}\cdot \frac{11\not0}{1\not0\not0}\cdot \frac{11\not0}{10\not0}\cdot\frac{11\not0}{100}=\boxed{161,051\,lei}$
