A group of adults plus one child attend a movie at Cineplex 15 tickets cost nine dollars for adults and six dollars for children the total cost for the movie $78 right and equation to find the number of adults in the group

There are 8 adults in the group.

Step-by-step explanation:

Let the number of adults in the group be 'x'.

Given:

Number of children = 1

Number of adults = 'x'

Cost for a ticket of adult = $9

Cost for a ticket of a child = $6

Total cost = $78

Total cost is equal to total cost of tickets of 'x' adults plus cost of ticket of 1 child.

Unit cost of 1 adult × Number of adults + cost of ticket of 1 child = Total cost

Framing in equation form, we get:

Adding -6 on both sides, we get:

Dividing both sides by 9, we get:

Therefore, there are 8 adults in the group.

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
