You take a group of 20 people going to the movies. kids' tickets
cost $ 4.- each, and adults tickets $ 6.- each. your total cost is $
96.- . the number of kids in your group is
hint: set up and solve a linear system.

The number of kids in group is 12

Solution:

Let "k" be the number of kids

Let "a" be the number of adults

Cost of 1 kid ticket = $ 4

Cost of 1 adult ticket = $ 6

You take a group of 20 people going to the movies

Therefore, we frame a equation as:

number of kids + number of adults = 20

k + a = 20 ----------- eqn 1

Your total cost is $  96

Therefore, we frame a equation as:

number of kids x Cost of 1 kid ticket + number of adults x Cost of 1 adult ticket = $ 96

4k + 6a = 96 ---------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

k = 20 - a ------ eqn 3

Substitute eqn 3 in eqn 2

4(20 - a) + 6a = 96

80 - 4a + 6a = 96

80 + 2a = 96

2a = 16

Substitute a = 8 in eqn 3

k = 20 - 8

Thus number of kids in group is 12

answer: c i think

step-by-step explanation:

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
