Suppose you sign a contract with a supplier for $50,000 worth of tablet computers. You tell the supplier that you are only authorized to sign contracts for $40,000 without approval from the supply manager of your company, but the supplier agrees anyway. A few days later, because of budget cutbacks, you find out that you only need $30,000 worth of tablet computers. How many dollars of tablet computers are you legally bound to purchase from the supplier?
