Answer: $30,000
Explanation:
Company estimates that 60% of boxtops will be redeemed.
They sold 500,000 boxes
= 500,000 * 60%
= 300,000 boxtops will be sent in.
So far, 220,000 have been sent in. How many left;
= 300,000 - 220,000
= 80,000 boxtops are still to be sent in
4 boxtops are needed to receive a pottery bowl so with 80,000;
= 80,000/4
= 20,000 pottery bowls are due to be issued. 
Each bowl costs $2.50 to make.  Customers will send in $1 however so effectively it will cost the company;
= 2.50 - 1 
= $1.50
With 20,000 still left to be issued, each costing $1.50, the total liabilitiy for outstanding premiums to be recorded at the end of 2007 is;
= 20,000 * 1.5
= $30,000

How will the general ledger accounts in the trial balance most likely differ if the company were a retail store rather than a wholesale company?
A general ledger account is used to record transactions that a company has. A trial balance has all of the general ledger accounts listed shows all of the debits and credits that a company has faced. A retail store will have smaller product transactions over a wholesale store due to the wholesale store selling in bulk. There will likely be more credits and debits for a retail store whereas a wholesale store may have more debits as they are less likely to have returns. 
How will they differ for a hospital or a government unit?
A hospital or government unit will have vastly different general ledger reports due to the type of agency they are. These transactions will deal more with insurance or big dollar companies rather than individuals on a smaller scale. A trial balance is not a financial statement but it used to show balances that an organization has.
