For every dollar of sales charged to a certain bank credit card, a department store must pay $0.003 to the bank that issued the credit card. What percentage of the department store's sales transactions last month were credit card transactions?
(1) The store made 2,000 sales last month.
(2) The store took in a total of $250,000 last month and paid $300 to the bank that issued the credit card.

We need Credit card transactions / total transactions:
(1) The store made 2,000 sales last month.We do not know that total number of credit card transactions:
INSUFF. (2) The store took in a total of $250,000 last month and paid $300 to the bank that issued the credit card.Using this we can calculate the total number of credit card transactions.
However it is not possibe to get the overall total number of transactions:
INSUFF. 1+2
From 1 we know the total number of transactions
From 2 we know the total number dollars that we got using credit card . ( 300/.003 )
However we still did not know the number of credit card transactions.
INSUFF.Ans E
