# Cash register final project

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){
}
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

``````if (change >= cidTotal)
`change` and `cidTotal` are both `50` in the case of this call
