Margo donated $4300 to Jayden's fundraising campaign. If Julie donated $4700 to Jayden's campaign, What's half the difference in the amount they contributed? Give me reasons, before answering the question
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.
