Final answer:
To raise more than 700 dollars, the class of 2024 needs 250 adults to attend the movie night.
Step-by-step explanation:
To calculate the number of adults needed to raise more than 700, we need to determine the average amount each student raises. From the given information, we can assume that each student needs to raise the same amount. Let's assume each student needs to raise x amount. Since there are 250 students and their total amount raised needs to be more than 700, we can set up the equation 250x > 700. To solve for x, we divide both sides of the equation by 250: x > 2.8.
To find out how many adults are needed, we divide the total amount needed by the amount each student needs to raise: 700 / 2.8 = 250. Therefore, 250 adults must attend the movie night for the class of 2024 to raise more than 700.
