Answer :
There was no offer made
Explanation :
From the statement made by Paul,
"I think... " there was no offer made here . Paul did not make any commitments because the statement started with "I think" and so there is no conclusive offer and we cannot conclude that Paul has made an offer here. We could however say that Paul may be inviting an offer and not making an offer since Barbie could now say she wants to buy for a certain price
