Well how long is the ribbon? I'm not asking for the dollar amount, I will answer your question if you can tell me the length of the ribbon. No one can figure it out unless you give the total length.
Answer:
18x = 7.2
x =.4
Step-by-step explanation:
Let x = the weight of one box
We have 18 boxes that weigh 7.2 lbs
18x = 7.2
Divide each side by 18
18x/18 = 7.2/18
x =.4
The slope is roughly -6/1
I graphed the equation y= -6/1x+4 and it looked pretty similar to the graph on your screen I hope this helps :)
It goes by 3s so I think its 1.2
