A woman can invest some money at 10% simple interest or at 8% compound interest. If she invests $8000 for 3 years, find which is the more profitable investment and by how much.

3/12 percent

Step-by-step explanation:

y=1/4x-4

step-by-step explanation:

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. : )
