Ibought 3 t-shirts and 4 sweatshirts for $79. my friend bought 8 t-shirts and 2 sweatshirts at the same store for $98. how much is each t-shirt and each sweatshirt

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. : )
