Question

Last Monday, two law students met up at café Literatura after school to read the pages they were assigned in the legal methods class. Alejandro can read 1 page per minute, and he has read 28 pages so far. Carly, who has a reading speed of 2 pages per minute has read 12 pages so far.

Part A: Define the variables and write two equations to represent the number of pages that each student read.

Variables:

Alejandro:

Carly:

Answer 1

Answer:

Step-by-step explanation:

Variables:

let x be the number of minutes

let y be the total number of pages read

Use the form y = mx + b

"b" is irrelevant in this context because the initial value is 0 (they have not read it before or it is not given)

m is the rate, how fast they can read, how many pages each minute

Alejandro:

28 = 1x   <=Simplify because any number multiplied by 1 is itself.

28 = x

Carly:

12 = 2x
