Question

Seth and Jennifer are trying to figure out how long they can live off their $22,500 savings if they spend $530 each month. They have each created an equation.
Seth’s Equation Jennifer’s Equation
y = 22,500 + (530x) y = 22,500 − (530x)


Which person has the correct equation to model this linear relationship?

Jennifer’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.

Jennifer’s equation is incorrect, because their spending will increase the amount of their savings.

Seth’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.

Seth’s equation is incorrect, because their spending should be a fixed amount and should not be multiplied.

Answer 1

Jennifer is correct- first one

Answer 2

Answer:

option A : Jennifer’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.

Step-by-step explanation:

Given :Their $22,500 savings if they spend $530 each month.

To Find : Seth and Jennifer are trying to figure out how long they can live off

Solution:

let they spend money for x months.

Since they spend in one month = $530

They spend in x months = 530x

Since they had savings of 22500 out of which they already spent $530x, So, remaining amount 'y' = 22500-530x

This equation same as Jennifer's equation.

SO, Jennifer is correct

Thus option A is correct :Jennifer’s equation is correct, because their spending will be multiplied by the number of months and then subtracted from their savings.
