Twenty years ago, Bruce Wayne bought a batmobile for 250 million dollars. As the crime in Gotham city

has been down for a while, he plans to sell it.

How much can he get for the batmobile if the price goes down by 20% every decade?

million dollars

Bruce will get 160 million dollars for the batmobile.

Step-by-step explanation:

100% - 20% = 80%

80% of N = 80/100 x N = 4/5 N

N = 250 x 4/5 x 4/5

   = 16/25

   = 160

i would pic false cause it goes down towards negative

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. : )
