b) How many days did it take for the average household to produce 200 pounds of garbage?

Answer 1

What do you need help with?
Do you know how to plot points on a graph?
Do you know how to isolate a variable?

Answer 2

I am lost trying to find variables for the graph.

Answer 3

Okay so for graphing an equation the first thing you wanna do is find some points to graph. We can do this by filling in a T chart. Would you be able to fill in the A column?

Answer 4

When you've done that you want to plot those points in a graph. Your axis this time will not be x and y, but instead t and A.

Answer 5

Ok, that is exactly what I done but it didn't feel like the right answer to plotting on the graph. :D

Answer 6

One way you can check is with wolframalpha.

It should look a bit similar, but I think you did it right.

Answer 7

Do you need help with part b?

Answer 8

I guess because I fail to substitute x-y for a-t.. and yea the second part really has me stumped also.
