Hi please advice where i have gone wrong

please see link

https://www.freecodecamp.org/learn/javascript-algorithms-and-data-structures/javascript-algorithms-and-data-structures-projects/cash-register

function checkCashRegister(price, cash, cid) {
  let change = cash*100 - price*100;
  let cidTotal = 0
  for (let elem of cid){
    cidTotal += elem[1]*100
  }
  if(change > cidTotal){
    return {status: "INSUFFICIENT_FUNDS", change: []}
  }else if (change === cidTotal){
    return {status: "CLOSED", change:cid} 
  }else{
    let answer = []
    cid=cid.reverse()
    let moneyUnits = {"ONE HUNDRED":10000, "TWENTY": 2000,"TEN": 1000, "FIVE": 500, "ONE": 100, "QUARTER": 25,"DIME":10,"NICKEL": 5, "PENNY":1};
for(let elem of cid){
  let holder = [elem[0],0]
  elem[1]=elem[1]*100
  while (change >= moneyUnits[elem[0]] && elem[1] > 0){
    change -= moneyUnits[elem[0]]
    elem[1] -= moneyUnits[elem[0]]
     holder -= moneyUnits[elem[0]]/100
  }
if (holder[1]>0){
  answer.push(holder)
}

  if (change > 0){ return {status: "INSUFFICIENT_FUNDS", change: []}

  }
  return{status: "OPEN", change: [answer]

  }
  
}
  }
 
}

checkCashRegister(19.5, 20, [["PENNY", 1.01], ["NICKEL", 2.05], ["DIME", 3.1], ["QUARTER", 4.25], ["ONE", 90], ["FIVE", 55], ["TEN", 20], ["TWENTY", 60], ["ONE HUNDRED", 100]]);

  //holder -= moneyUnits[elem[0]]/100
    holder[1] += moneyUnits[elem[0]] / 100;
	

it is subtracting the value of the currency unit from the holder array instead of adding it
