Part A: Define the varibles and write two equations to represent the number of pages that each student reads

Varible:
Alejandro:
Carly:

Answer 1

Variable:
x= # of pages
Alejandro:
1 (x)=28
Carly:
2 (x)=12

Answer 2

Variable: x ( total time )

Alejandro:
`28= 1*x`

Carly:
`12=2x`

Explanation:

Given :

Alejandro can read 1 page per minute.

He has read 28 pages so far.

Carly can read 2 pages per minutes and has read 12 pages so far.

Solution :

Let x denotes the time taken by each student.

Variable = x

Since Alejandro can read page in 1 minute = 1

He can read 28 pages in x minutes .

Since he read total 28 pages . So, equation becomes :

`28= 1*x`

Since Carly can read 2 pages per minutes.

He has read 12 pages in x minutes

So, equation becomes :

`12=2x`

Variable: x ( total time )

Alejandro:
`28= 1*x`

Carly:
`12=2x`
