Answer 1

Step-by-step explanation:

First we must know what data the exercise gives us; for exmple:

-Tells us that it reads a number of pages (unknown data) each month or per month.

-The exercise asks us, how many pages will have been read after 4 months.

We can see that we first have to find the number of pages in a month and then find the number of pages in 4 months.

The exercise is as follows:

`\begin{gathered} p\rightarrow pages\text{ read; ( }in\text{ a month)} \\ x\rightarrow4\text{ months} \\ x=(4*(30))/(1(30))=4.000\colon\text{ estimate } \\ \text{ANSWER:The correct option is A ; 4.000 Estimate (}we\text{ say }this\text{ because} \\ we\text{ do not know }exactly\text{ }the\text{ actual numbers of pages; }that\text{ is }why\text{ we} \\ \text{take }the\text{ 30 days }of\text{ the month }as\text{ a }probability) \end{gathered}`
