How much did I spend on my 12$ meal with 5% tax and a 15% tip left after

$14.49

Step-by-step explanation:

Since the question asked you how much you spent on the meal including the 5% tax and the 15% tip after the tax, it's basically asking you to calculate the percentage of the meal and subtracting it by the amount.

you can't solve x because it is 2 linear equation and you only have one equation

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. : )
