Answer:
7
Step-by-step explanation:
take the second term and minus first then take the third and minus the second take the fourth and minus the third then you will find your constant difference
X=1 because -7 times 1 = -7
Package A = $276 for 12 tickets (2 x 6) // 276 divided by 12 = $23 per ticket
Package B = $336 for 16 tickets (2 x 8) // 336 divided by 16 = $21 per ticket
$23 - $21 = $2
Package A charges $2 more per ticket.
C=pi x D
9.04= pi D
D=9.04/pi
or= 2.87
