Wendy sold a commercial building to Ann, an educated person. Ann merely half-read the contract that she signed. As a result, she did not notice the provision in the contract about 

the interest on the purchase price. Ann refused to pay the interest specified in the contract, and Wendy sued her. Ann's argument is that Wendy never told her of the interest provision in the contract, and she should not be liable. Is Ann correct? Why or why not?
