I don't do good with slope intercept, but I can tell you that Fit n Trim would be $80m and Fit for Life would be $75+55m.
First markdown: 0.75($500) = $375
Second markdown: 0.75($375) = $281.25
Third markdown: 0.75($281.25) = $210.94
It would be 16 minutes because you would divide 80 by 20 and you get 4 so now you multiply 4 by 4 and you get 16
x-axis is y=0, so the answer is D.
but not D. Luffy
By the graph of a straight line through the origin with a slope equal to the unit rate
