Question

Una compañía de telefonía móvil en expansión ha gestionado durante el trimestre que finaliza ochocientas cincuenta mil llamadas al día. En el próximo trimstre espera llegar al millón e ir aumetado trimestralmente en la misma cantidad durante los próximos dos años. ¿Cuántas llamadas diarias espera gestionar dentro de dos años?

Answer 1

Answer:

$2,050,000\ daily\ calls$

Step-by-step explanation:

The question in English is

An expanding mobile phone company handled eight hundred and fifty thousand calls a day during the quarter. In the next quarter it expects to reach one million and increase quarterly by the same amount over the next two years. How many daily calls do you expect to handle in two years?

Let

x ----> the number  of quarter

y ---> number of daily calls

we know that

we have the points

(0,850,000) and (1,1,000,000)

Find the slope m

$m=(1,000,000-850,000)/(1-0)=150,000\ daily\ calls$

The linear equation that represent this situation is

$y=150,000x+850,000$

How many daily calls do you expect to handle in two years?

In two years there are 8 quarterly

so

For x=8

substitute

$y=150,000(8)+850,000=2,050,000\ daily\ calls$
