Answer:
$50/student.
Step-by-step explanation:
The 83 members of the Newman Middle school have already raised $850 of the total $5,000 needed to buy new percussion instruments. To find out how much is left to raise, we must subtract that $850 from the total $5,000 needed, which leaves us with $4,150.
The question is asking us how much should each student raise on average to meet the goal. They tell us there are 83 members, and we know, from our calculations, that there are $4,150 left to raise. Thus, we can divide the $4,150 by the 83 members to find our answer of how much money each student, on average, will have to raise.
4,150/83 = 50. Hence, each student will have to still raise, on average, $50 to meet the goal of $5,000.
