The store has a stock of 12 AA batteries and 15 9V batteries. So, these are the limits of the batteries that Mrs. Gibbs can only buy. She already bought 7 pieces of AA batteries. Then, she needs to buy only at least 20 batteries. Therefore, she should buy all of the stock of AA batteries which is 12 pieces.
