Question

HURRY PLS!! Jacob and kerrie are trying to figure out how long they can live off their 84,670 savings if they spend 370 each month. they have created an equation. jacobs equation is y=84,670+(370x). Kerrie's equation is y=84,670-(370x).

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

A.)Kerrie's equation is incorrect because their spending will increase their amount of savings
B.)Kerrie's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings
C.)Jacobs equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings.
D.)Jacobs equation is incorrect because their spending should be a fixed amount and not multiplied.

Answer 1

The answer is B. Kerrie's equation is correct

Answer 2

B.)Kerrie's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings

Explanation:

Given : Jacob and kerrie are trying to figure out how long they can live off their 84,670 savings if they spend 370 each month.

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

Jacob's equation : y = 84,670+(370x).

Kerrie's equation : y=84,670-(370x).

Since they have 84670 in savings

They spend each month = 370

They spend in x months = 370x

So, spending this amount from saving they left with amount = 84,670-(370x)

Thus Kerrie's equation is correct .

Hence Option B is correct

B.)Kerrie's equation is correct because their spending will be multiplied by the number of months and then subtracted from their savings
