Answer:

Step-by-step explanation:
We are given the following in the question:
Controller cost = $135
System cost = $2.50 per foot of pipeline
The total cost depends upon the length of Pole.
Let the system requires F feet of pipeline.
Total cost will be given by the equation:

is the required expression for total cost
F: feet of pipeline required
c(F): Total cost of installation
 
        
             
        
        
        
Answer:
Step-by-step explanation:
Convert 6 hours to minutes so that 6 hours and 16. 3 minutes can be in the same units.
Since 1 hour = 60 minutes, then 6 hours = 6 x 60 minutes = 360 minutes
Since the insect has more minutes to crawl (360 minutes), then we expect more inches to be covered. Therefore, the ratio is 360 minutes to 16.3 minutes
= 360 minutes : 16.3 minutes
= 360 : 16.3  
Now express the ratio as fraction and relate it with 30 inches
 = 360/16.3  x  30/1
= 10800/16.3
= 662 .576687 and this is approximately 650 inches
Answer  = 650 = (C)
