Question

a que taxa mensal devo empregar um capital de r$ 20.000 para que no fim de 10 meses renda 18.000 de juros

Answer 1

Following are the solution to the given question:

Explanation:

`\to 18000=2000 * i * 10 \\\\\to 18000=200000 * i\\\\\to i=(18000)/(200000)\\\\\to i= (18)/(200)\\\\ \to i= (9)/(100)\\\\ \to 0.09\\\\`

Calculating the percentage:

`\to 0.09* 100=9\%`
