At one movie theater, it costs $8 per person for a ticket and an additional $4 for a bucket of popcorn for a group of friends to share. At another movie theater, it costs $7 per person for a ticket and $8 for a bucket of popcorn for the group to share. If the group of friends paid the same total amount of money at both movie theaters, how many people are in the group?

h = 4 people

Step-by-step explanation:

Let

x = number of people in the group

Theater 1:

it costs $8 per person for a ticket and an additional $4 for a bucket of popcorn for a group of friends to share.

8h + 4

At another movie theater, it costs $7 per person for a ticket and $8 for a bucket of popcorn for the group to share

7h + 8

Equate both theater cost

8h + 4 = 7h + 8

8h - 7h = 8 - 4

h = 4 people

Therefore, there are 4 people in the group

= 5

step-by-step explanation:

to find the 15th term substitute n = 15 into the nth term formula

= (- 3 × 15 ) + 50 = - 45 + 50 = 5
