Get specific Data from inside a HashMap

First of all I must apologies for I am uncertain how to word my title well.

However the problem I am facing is a continuation of another question that brought me one step closer to completing this particular program. Onto the problem though.

Here is my current output:

Income
{Jack=46, Mike=52, Joe=191}

These are inside the HashMap and I printed that out, what I need to do though is make this output more presentable and I guess that leads to needing to manipulate/get certain Data from inside the Map and then make it presentable.

The goal I am aiming for is to get my output to look like this:

Jack: $191
Mike: $52
Joe: $46

I'm still very new to Java and programming in general so I'm just wondering if this is possible or if I have tackled this all from the wrong way in the beginning?

Below is my code:

public static void main(String[] args) {

  String name;
  int leftNum, rightNum;

  //Scan the text file
  Scanner scan = new Scanner(Test3.class.getResourceAsStream("pay.txt"));

  Map < String, Long > nameSumMap = new HashMap < > (3);
  while (scan.hasNext()) { //finds next line
    name = scan.next(); //find the name on the line
    leftNum = scan.nextInt(); //get price
    rightNum = scan.nextInt(); //get quantity

    Long sum = nameSumMap.get(name);
    if (sum == null) { // first time we see "name"
      nameSumMap.put(name, Long.valueOf(leftNum + rightNum));
    } else {
      nameSumMap.put(name, sum + leftNum + rightNum);
    }
  }
  System.out.println("Income");
  System.out.println(nameSumMap); //print out names and total next to them

  //output looks like this ---> {Jack=46, Mike=52, Joe=191}

  //the next problem is how do I get those names on seperate lines
  //and the total next to those names have the symbol $ next to them.
  //Also is it possible to change = into :
  //I need my output to look like below
  /*
      Jack: $191
      Mike: $52
      Joe: $46
  */
}

}
