const purchaseItems = [

},
{

dept: 'apparel',
price: 9.99
}
];
let groceryTotal;
groceryTotal = purchaseItems
.filter((debts, prices) => debts.debt == 'groceries' + prices.price)
.reduce((sum,prices ) => sum + prices.price , 0);
console.log(groceryTotal)
// groceryTotal should be: 9.47
// Write your code below

231,172 PointsYou're close, but there's a few issues:
- the callback in "filter" gets only one argument
- you have "debt" instead of "dept" (with a "p")
- the price won't be involved in the filter
- the "sum" should be included with the price in the "reduce" expression
