setIndex(pageInfo: PageInfo, index: number) {
    return (
      pageInfo?.totalItems -
      (index + 1 + pageInfo.itemsPerPage * (pageInfo.currentPage - 1)) +
      1
    );
  }

<div
  *ngFor="let inquiry of mockInquiries | paginate:
{ itemsPerPage: pageInfo.itemsPerPage, currentPage: pageInfo.currentPage, totalItems: pageInfo.totalItems};index as i"
  class="flex w-full cursor-pointer"
  [routerLink]="['./', inquiry.count]"
>
  <div class="flex basis-1/12 py-4 pl-4 items-center">
    {{setIndex(pageInfo, i)}}
  </div>
  <div class="flex
