Each cap would be about $8.44. Equation to model this problem is 270/x=y or c for caps
        
             
        
        
        
I'm not exactly sure, so if I'm wrong please correct me.
The equation is 2kg + x = s

1) Circumference of Earth: Diameter x π → 12,800 x π = 40,212.39 km 
2) time in Hour = distance/speed → distance = 40,212.39 and speed = 2 Mi/h 
1st: convert miles into km : 1 mile = 1.609344 km and 2 miles = 3.218688 km
2nd: convert speed into km/h → speed = 3.218688 km/h
And time in hour = 40,212.39 / 3.218688 → time = 12,493 hours  OR in days:
12,493 / 24 = 521 days (OR 104 weeks, including 2 days of rest)

The slope of the graph is 3
The y-intercept is -4
The equation of the line is y=3x-4 it shouldn’t be y= then x=
