Solve Variation Problem
The cost of pipe at Home Depo varies jointly as the length and
diameter of the pipe.

c = k

If 20 feet of 0.5 inch diameter pipe
costs $36.60
Solve for "k":
36.60 = k[20*0.5]
k = 36.60/10 = 3.66
---
Equation:
c = 3.66[Ld]
---
, then what is the cost of 12 feet of 0.75 inch
diameter pipe?
---
c = 3.66[12*0.75]
cost = 3.66*9
cost = $32.94
