Check Your Receipts Have you ever helped with the
shopping? Groceries are a big expense for most
families. Some people use a calculator when they
shop. As they pick each item, they punch in the
price. They may know their total even before they
reach the checkout.
Some people watch as each item is added to the
total. A mistake of one decimal place can make a
big difference. For example, a $0.59 item could be
read as $5.90. How much would a mistake like this
cost?
Computer checkouts have helped to prevent some
mistakes. However, some people still check their
receipts very carefully. The next time your family
brings home a grocery receipt, check the total with
a calculator. You should also read each item to
check for other mistakes. What other mistakes
might be found on a grocery receipt?
