Answer
Each student has to raise $225 on average.
Step-by-step explanation
The students already saved $1250 out of their goal of $12,500
So, the amount still left to raise is
$12,500 - $1250 = $11,250
Let the amount each student will save on average be x dollars
Since there are 50 students in all, we can solve for x thus
x = ($11,250/50) = $225
Hope this Helps!!!
