Final answer:
To replenish the petty cash fund to $100, the correct entry is to debit Cash Over and Short for $2. This entry corrects the $2 shortfall in the petty cash fund, taking into account the $90 in receipts and $8 in cash already present.
Step-by-step explanation:
The question involves replenishing a petty cash fund and recording the associated financial transaction. When a cheque is written for $2 to bring the cash up to $100 ($90 in receipts + $8 in cash already in the fund), the correct entry is to debit Cash Over and Short for $2. This addresses the shortfall from the expected fund amount. The petty cash fund should be back to its original amount of $100 after this transaction, with the $90 of receipts accounting for the disbursements and the total cash replenished to $10.
