Cash register final project

JavaScript
1

Hi! I need some help please.

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 result = []
    cid = cid.reverse()
    let unidades = {
      "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 temp = [elem[0], 0]
      elem[1] = elem[1]*100
      while(change >= unidades[elem[0]] && elem[1] > 0){
        change -= unidades[elem[0]];
        elem[1] -= unidades[elem[0]];
        temp[1] += unidades[elem[0]]/100;
      }
      if(temp[1] > 0){
        result.push(temp)
      }
    }
    if (change >0){
      return {status: "INSUFFICIENT_FUNDS", change: []}
    }
    return {status: "OPEN", change: result}
  }
}

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]]);

And the error say

// ejecutando pruebas
checkCashRegister(19.5, 20, [["PENNY", 0.5], ["NICKEL", 0], ["DIME", 0], ["QUARTER", 0], ["ONE", 0], ["FIVE", 0], ["TEN", 0], ["TWENTY", 0], ["ONE HUNDRED", 0]]) debe devolver {status: "CLOSED", change: [["PENNY", 0.5], ["NICKEL", 0], ["DIME", 0], ["QUARTER", 0], ["ONE", 0], ["FIVE", 0], ["TEN", 0], ["TWENTY", 0], ["ONE HUNDRED", 0]]}.
// pruebas completadas
2 
if (change >= cidTotal)

change and cidTotal are both 50 in the case of this call

checkCashRegister(19.5, 20, [["PENNY", 0.5], ["NICKEL", 0], ["DIME", 0], ["QUARTER", 0], ["ONE", 0], ["FIVE", 0], ["TEN", 0], ["TWENTY", 0], ["ONE HUNDRED", 0]])

Thanks a lot. I resolved in the last week. Cheers
