Answer:
$33.85
Step-by-step explanation:
Let X be the initial bill:
(100 + 20.7)% of X was paid

X = 40.86 × 100/120.7
X = 33.85252693
Answer: 600 students
Step-by-step explanation:
Of the total number of sixth graders who were surveyed, 5% owned birds.
This 5% translated to 30 students.

Assume that number to be x:
x * 5% = 30
x = 30 / 5%
= 600 students
