Question

Hace 6 años compre un lote en $900.000, recibí un interés por la inversión $1.423.000, hallar la tasa de interés de este negocio

Answer 1

Interest rate, R = 26.35%

Step-by-step explanation:

Given the following data;

• Time = 6 years
• Principal = $900,000
• Simple interest = $1,423,000

To find the interest rate, we would use the following formula;

`S.I = \frac {PRT}{100}`

Where;

• S.I is the simple interest.
• P is the principal.
• R is the interest rate.
• T is the time measured in years.

Making "R" the subject of formula, we have;

`R = \frac {100S.I}{PT}`

Substituting the values into the formula, we have;

`R = \frac {100 * 1423000}{900000 * 6}`

`R = \frac {142300000}{5400000}`

Interest rate, R = 26.35%

Therefore, the interest rate of this business is 26.35 percent.
