Write a c++ program to determine which car rental would be the cheapest depending on how far the car is driven. Package A is 15.99 then 45 cents per mile, B is 19.99 then 30 cents per mile package c in 29.99 with unlimited driving. Ask the user what plan they picked and then how far they drove. The output should show which option could haves saved them money and how much. Shown their bill formated with a dollar sign and two decimal places. Then display if they had purchased other packages that would have saved money, how much they would have saved. Honestly I have no clue where to begin with this so anything helps.
