PTION #3(20pts): The last option is by Plane Cargo. You cannot seem to find rates on their website, but a service representative was able to tell you that a 100-mile flight will cost $600, and a 250-mile flight will cost $825.

Rate for 100 miles = $ 6 / miles

Rate for 250 miles = $ 3.3 / miles

Step-by-step explanation:

Given that cost for covering 100 miles by flight is $600.

As rate is the cost of covering unit distance (in miles).

So, the rate to cover 100 miles by flight = $ 600/ 100 miles = $ 6 /miles.

Similarly, the cost of covering 250 miles by flight is $825.

So, the rate to cover 250 miles by flight = $ 825/ 250 miles = $ 3.3 /miles.
