Jan has $130. she saves $25 per week. write and solve an equation to determine how many weeks it will take for her to have $600

The equation needed to save this amount is A = 25x + 130, where A is the total amount had and x is the amount of weeks from the start.

You can find this equation by noting that even at 0 weeks, she has 130. Then the rate of growth (which needs to be multiplied by weeks) is 25.

To solve this for $600, we simply put in 600 for A and solve for x.

A = 25x + 130

600 = 25x + 130

470 = 25x

18.8 = x

So if we are rounding up to whole weeks, it would take 19.

it is a. 4.2 because 7.6-3.4 gets the remaining length of 4.2. i might be wrong but i am pretty sure this is the answer.

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )
