Question

En un laboratorio hay 20,000 bacterias al principio (hora 0), si cada hora incrementan en un 25%, cuantas bacterias abra al cabo de 6 horas ???

Answer 1

Respuesta:

76,295 bacterias

Explicación paso a paso:

Hora 0: 20,000 bacterias

Hora 1: 20,000 bacterias +25% = 20,000+5,000 = 25,000 bacterias

Regla de tres:

• 20,000 -------------100%
• x1 ------------------------25%

x1 = 20,000*25/100

x1 = 5,000

Hora 2: 25,000 bacterias +25% = 25,000+6,250 = 31,250 bacterias

Regla de tres:

• 25,000 -------------100%
• x2 ------------------------25%

x2 = 25,000*25/100

x2 = 6,250

Hora 3: 31,250 bacterias +25% = 31,250+ 7,813= 39,063 bacterias

Regla de tres:

• 31,250 -------------100%
• x3 ------------------------25%

x3 = 31,250*25/100

x3 = 7812.5 ≈ 7813

Hora 4: 39,063 bacterias +25% = 39,063 + 9,766 = 48,829 bacterias

Regla de tres:

• 39,063 -------------100%
• x ------------------------25%

x4 = 39063*25/100

x4 = 9,765.75 ≈ 9,766

Hora 5: 48,829 bacterias +25% = 48,829 + 12,207 = 61,036 bacterias

Regla de tres:

• 48,829-------------100%
• x5 ------------------------25%

x5 = 48,829*25/100

x5 = 12,207.25 ≈ 12,207

Hora 6: 61,036 bacterias +25% = 61,036 + 15,259 = 76295 bacterias

Regla de tres:

• 61,036 -------------100%
• x6 ------------------------25%

x6 = 61,036*25/100

x6 = 15,259
