Miss Peach, fourth grade teacher at Kelly School, wants to set up a school store in her classroom. This is to be a store like none other. Miss Peach wants to bring the school store into the 21st century, with all transactions to be handled electronically: students will have access to a classroom "ATM" to monitor their checking and savings account, the store will be able to buy and sell items by crediting and debiting the student accounts, and the teacher will be able to pay weekly salaries and bonuses to the student accounts using direct deposit. No real money is involved and Miss Peach has limited resources, so the store must be self-sufficient. Miss Peach uses the computer regularly to keep her grade book and to generate work sheets, but she needs your help to design this system
