Answer:
Equivocal Acceptance.
Explanation:
As Mandy decided to sell her iPad and made an offer for $250 to her friend Shelly. Shelly told Mandy she was willing to buy the iPad, but she would be glad if Shelly could lower her asking price. Mandy lowered the price to $210 and Shelly bought it. Equivocal acceptance describes Shelly's response to Mandy for her first offer. Equivocal is the word which means using one single word but in different meanings. She has used this word to give double meanings to it. First she has used it that she will buy only the price will be lowered and secondly that word also lead Mandy to accept her offer as well. Shelly has used this word quite intelligently and effectively.
