How does Capulet respond to Paris proposal to marry Juliet?

At first he doesn't think it's a good idea because she's too young and is his only child, but if Paris can sweep her off her feet when he has the ball then yes.

The first time Paris offers for her hand in marriage Capulet says if he can sway her to love him Paris may marry Juliet.

The second time Paris offers for her hand Capulet accepts on Juliet's behalf and sets the wedding for Thursday of that week.
