Answer:
$66.
Step-by-step explanation:
Inversely Proportional, so C = k/n where C = the cost per person, n is the number of people and k is a constant to be found:
Inserting the given values:
30 = k/44
So k = 30*44 = 1320 and the equation of variation is
C = 1320/n.
When 20 people are on the trip we have:
C = 1320/ 20
= $66.
