 <translate> If Julie donated $4700 to Jayden's campaign, and Margo donated $4300, the difference in their contribution is $4700 - $4300 = $400. Half the difference in the amount they contributed is 1 / 2 * $400 = $200. So the final answer is 200. <yor> Bí Julie bá fi $4700 ṣètọrẹ fún ìpolongo Jayden, tí Margo sì fi $4300 ṣètọrẹ, ìyàtọ̀ nínú ọrẹ wọn ni $4700 - $4300 = $400.
