Answer:
a=20
Step-by-step explanation:
4a+8-2a-3=45
-8 on both sides
4a-2a-3=37
+3 on both sides
4a-2a=40
2a=40
a=20
The cost per person if number of students is 100 given the inverse variation is $46.75
<h3>Inverse variation</h3>
- Cost per person = C
- Number of students = n
C = k / n
where,
- k = constant of proportionality
If n = 55 and C = $85
C = k / n
85 = k / 55
85 × 55 = k
4,675 = k
Find C if n = 100
C = k / n
= 4,675 / 100
C = $46.75
