Answer:
$50
Step-by-step explanation:
First you subtract 850 from 5000 to find out how much money the students have left to raise. You should get $4150. You then divide 4150 by the 83 students and you find that each student is responsible for raising $50.
????????????
7.50= (1 + x/100 ) × 5.50
7.50/ 5.50 = 1+x/100
x/100 = 0.36
x= 36.36%
Answer: 3 ( x + 7 )
=5
