A=P(1+r)^t
18600=1000(1+0.0675)^t
18600/1000= (1.0675)^t
18.6= (1.0675)^t
log 18.6 = t log 1.0675
t= log 18.6/ log 1.0675
t=44.75 years

Alja [10]

Answer:

900

Step-by-step explanation:

10% de 9000 es 900

Trabajando el 10% de 9000

Escribe 10% como 10100

Dado que, encontrar la fracción de un número es lo mismo que multiplicar la fracción por el número, tenemos

10100 de 9000 = 10100 × 9000

Por tanto, la respuesta es 900

Si está utilizando una calculadora, simplemente ingrese 10 ÷ 100 × 9000, lo que le dará 900 como respuesta.
