Let's say c is the cost of the cantaloupe, and that p is how many pounds the cantaloupe weights.
In that case, $1.19 is the amount of money it will cost per pound of cantaloupe.
If the cantaloupe you buy is 3.5 pounds, it will cost you $4.165, but since money is only two decimal places, and since you can only round up when it's a 5 at the end, it becomes $4.17.
In other words, each pound of cantaluope you buy will cost you $1.19, and a cantaloupe that weighs 3.5 pounds will cost you $4.17.
